Emulsion paints are based on aqueous synthetic resin dispersions, which afford a lacquer-like paint film. The resin dispersions which are commonly used by the paint industry contain water as the carrier phase. A large number of such dispersions are available, based on different resins such as poly(vinyl acetate), which may be employed as a copolymer with vinyl chloride, maleic dibutyl ester, ethylene, acrylic acid esters, polyacrylic resin, and copolymers of the latter with various monomers, as well as styrene-butadiene or poly(vinyl propionate). These disper-... [Pg.159]

The glass transition point of these materials decreases as the number of carbons in the alcohol increases. Thermal stability and pyrolysis products of polyacrylates have been thoroughly studied [23-29]. Some literature results regarding thermal decomposition of poly(acrylic acid esters) are summarized in Table 6.7.4 [6]. [Pg.349]

Upon attempting to extend this so-called group transfer polymerization to the more reactive acrylic acid esters, troubles were encountered Nucleophilic catalysts were not very efficient, and electrophilic catalysts such as ZnX2 delivered polyacrylates at room temperature which were no longer living. ... [Pg.121]

Polyacrylic elastomer is a chemically saturated polymer of acrylic acid esters. Since esters are rather inert, other groups such as epoxy, halogen and carboxyl must be incorporated into the polymer to introduce sites for curing. We have studied the effect of various ammonium and phosphonium salt catalysts on the rate of crosslinking of polyacrylic elastomers which contain carboxyl and epoxy groups as cure-sites. We find that the catalytic activity of onium salts correlates with nucleophilicity of their anions. [Pg.221]

Polyacrylates are an industrially important class of polymers. The name polyacrylate is variously used to refer to polymers of acrylate esters [e.g., poly(methyl methacrylate)] as well as polymers of acrylic acids [e.g., poly(meth-acrylic acid)]. Because the former is organic soluble while the latter is not, chromatographic analysis of these two requires quite different conditions. This chapter discusses both types of polymers, separating their consideration when necessary. We will refer to both types of polymers as polyacrylates, letting the context indicate whether we are referring to an ester or to an acid polymer. [Pg.539]

Brandt [200] has extracted tri(nonylphenyl) phosphite (TNPP) from a styrene-butadiene polymer using iso-octane. Brown [211] has reported US extraction of acrylic acid monomer from polyacrylates. Ultrasonication was also shown to be a fast and efficient extraction method for organophosphate ester flame retardants and plasticisers [212]. Greenpeace [213] has recently reported the concentration of phthalate esters in 72 toys (mostly made in China) using shaking and sonication extraction methods. Extraction and analytical procedures were carefully quality controlled. QC procedures and acceptance criteria were based on USEPA method 606 for the analysis of phthalates in water samples [214]. Extraction efficiency was tested by spiking blank matrix and by standard addition to phthalate-containing samples. For removal of fatty acids from the surface of EVA pellets a lmin ultrasonic bath treatment in isopropanol is sufficient [215]. It has been noticed that the experimental ultrasonic extraction conditions are often ill defined and do not allow independent verification. [Pg.80]

Acrylic acid and its salts are raw materials for an important range of esters, including methyl, ethyl, butyl, and 2-ethylhexyl acrylates. The acid and its esters are used in polyacrylic acid and salts (32%, including superabsorbent polymers, detergents, water treatment chemicals, and dispersants), surface coatings (18%), adhesives and sealants (15%), textiles and non-wovens (12%), plastic modifiers (5%), and paper coating (3%). [Pg.226]

Acrylic acid is almost exclusively used directly, or after conversion to an ester, as a monomer. Acrylate esters are produced by normal esterification processes. However, in dealing with acrylic acid, acrolein, or acrylates, unusual care must be taken to minimize losses due to polymerization and other side reactions such as additions of water, acids, or alcohols across the reactive double bond. Polyacrylic acids find use in superabsorbers, dispersants, and water treatment. The polyesters are used in surface coatings, textile fibers, adhesives, and various other applications. [Pg.380]

Poly(acrylates) and poly(methacrylates) form another class of common polymers with saturated carbon chain backbone. Polyacrylates can be considered vinyl polymers with the -COOR group attached at every other carbon atom in the chain. However, due to their common use and particular properties, polyacrylates form a separate polymer class together with polymethacrylates. Among the most common polymers from this class are those obtained from acrylic acid methyl ester (PMA) and methylacrylic (methacrylic) acid methyl ester (PMMA). Acrylic polymers have many practical applications in automotive industry, in the production of medical materials, paints, coatings and lacquers, adhesives, textiles, and synthetic leather. Poly(methacrylic acid methyl ester) can be obtained in cast sheets with applications in technical components, furniture, building materials, etc. Formulas for poly(acrylic acid), two polyacrylates, and poly(methyl methacrylate) are shown below ... [Pg.341]

For more than decades, acrylic acid has served as an essential building block in the production of some of our most commonly used industrial and consumer products. Approximately two-thirds of the acrylic acid manufactured in the United States is used to produce acrylic esters - methyl acrylate, butyl acrylate, ethyl acrylate, and 2-ethylhexyl acrylate -which, when polymerized, are ingredients in paints, coatings, textiles, adhesives, plastics, and many other applications. The remaining one-third of the acrylic acid is used to produce polyacrylic acid, or cross-linked polyacrylic acid compounds, which have been successfully used in the manufacture of hygienic... [Pg.45]

In addition to ABS, with polybutadiene as the elastifying component, there is another forerunner among the polymer products formulated for low-temperature impact resistance, PVC-U. Elastifying ligands include EVAC, EVAC/VC graft polymer, PAEA C (polyacrylic acid ester/vinyl chloride copolymer), ACE (acrylic ester/MMA graft polymer) as well as the chlorinated low-pressure polyethylene PE-C in use for over 35 years. All of the polymer blends listed here are suitable for outdoor applications since they contain no unsaturated components. Polybutadiene-modified products are better suited to interior applications, for example MBS, a methylmethacrylate/butadiene/styrene graft polymer [55]. [Pg.124]

Polyacrylate, a thermoplastic polymer, synthesized by polymerization of acrylate monomers, consists of acrylic acid (AA) esters shown in Figure 1 as the general stractirre. Methacrylate monomer differs from the acrylate monomer in that the H atom at the virtyl oxygen is substituted by a methyl group (-CH ). The wide variety of side chains and the variations in tactidty contribute to polyacry-... [Pg.506]

Polyacrylates are based on acrylic acid, methacrylic acid, and their esters. Among them, polymethylmethacrylate (PMMA) and polyhydroxy ethyl-methacrylate (PHEMA) have found wide applications as biomedical materials. The clinical history of polyacrylates began when it was unexpectedly discovered that the fragments of PMMA plastic aircraft canopies stayed in the body of the wounded without any adverse chronic reactions (Jones and Denning, 1988 Park and Lakes, 1992). [Pg.278]

Polyacrylate A polymer of an ester of acrylic acid or of esters of acrylic acid homologues or substituted derivatives. [Pg.736]

PAAm and PMAAm can also be obtained by polymer analogous step. Polyacrylate esters can react with amines to yield PAAm and PMAAm. Polyacrylonitrile can be saponified to a copolymer of acrylic acid salt and acrylamide. [Pg.282]

A patent d issued in 1952 described the use of copolymers of higher acrylate or methacrylate esters with acrylic acid or methacrylic acid in the preparation of improved pressure sensitive tapes and liners for adherent rubber surfaces. The carboxyl content of these copolymers was so high that they could be considered to be plasticized polyacrylic acids rather than carboxylic elastomers. [Pg.270]

Polymerization of propenoic (acrylic) acid and its derivatives produces materials of considerable utility. The polymeric esters (polyacrylates) are tough, resilient, and flexible polymers that have replaced natural rubber (see Section 14-10) in many applications. Poly(ethyl acrylate)... [Pg.564]

Another factor which can affect the soluble fraction is the relative reactivities of acrylic acid or sodium acrylate with the crosslinkers. As evidenced by reactivity ratios of various monomer pairs, methacrylate esters tend to be more reactive with acrylic acid and acrylate esters less reactive with acrylic acid. In a crosslinking copolymerization therefore, a methacrylate crosslinker will tend to be used up earlier in the reaction than will an acrylate crosslinker. As a result, use of methacrylate crosslinkers tends to give crosslinked polyacrylates with higher extractable fraction. [Pg.33]
