Acetate - Acrylic Terpolymer

This example illustrates a graft polymerisation in which colloid stabilisation and both Redox and thermal initiation techniques are employed. The reaction in effect takes place in two stages, with the vinyl acetate polymerisation taking place before the acrylic monomers are polymerised. 

Thus a random copolymer will not result and reaction conditions are such that grafting of the acrylates onto the vinyl acetate backbone occurs. The use of a colloid to emulsify the acrylic monomers discourages the formation of new particles and these monomers therefore polymerise within the vinyl acetate particles. 

The acrylic polymerisation is carried out in the presence of a high free radical concentration to favour the generation of sites for the grafting mechanism.

An aqueous phase is made by dissolving sodium octyl phenol +4EO sulphate in 60% of the water to which is added 20% of the ammonium persulphate and the sodium hydrosulphate followed by the tertiary butyl hydroperoxide.

Table 1 shows an example of the partial operating instructions and log for the preparation of a terpolymer of vinyl acetate, butyl acrylate, and vinyl neodecanoate. The details of these instructions will, of course, have to be individualized for specific situations. 

However, a method to improve the flow properties of such fuel oils of animal or vegetable origin, has been developed (26). This consists in adding a EVA copolymer or a comb polymer based on methyl acrylate and a-olefins. In addition, terpolymers of ethylene, vinyl acetate and isobutylene have been found to be useful as cold flow improvers (29). 

Copolymers of acrylonitrile and methyl acrylate and terpolymers of acrylonitrile, styrene, and methyl methacrylate are used as bamer polymers. Acrylonitrile copolymers and multipolymers containing butyl acrylate, ethyl aciylate, 2-ethylhexyl acrylate, hydroxyethyl acrylate, methyl methaciylate. vinyl acetate, vinyl ethers, and vinylidene chlonde are also used in bamer films, laminates, and coatings. Environmentally degradable polymers useful in packaging are prepared from polymerization of acrylonitrile with styrene and methyl vinyl ketone. 

Special vinyl acetate copolymer paints have been developed with greatly improved resistance to blistering or peeling when immersed in water. This property allows better cleaning and use in very humid environments. These lattices exhibit the water resistance of higher priced acrylic resins (150). VAc, vinyl chloride—ethylene terpolymers have been developed which provide the exterior resistance properties of vinyl chloride with the flexibility of the ethylene for exterior paint vehicles (151). 

Rau [2] prepared terpolymers of ethyl ot-acetoxyacrylate, acrylic acid, and vinyl acetate that were used as bleach stabilizers in phosphate-free laundry detergent formulations.

Pentachlorophenyl acrylate, (1), was terpolymerized with methyl methacrylate (MMA) and n-butyl acrylate (nBA) (Scheme III) to give a latex containing 537 solids and a pll of 4.7 which was adjusted to 6.8 by adding aqueous NaOH. The latex was stable up to pH =10. A small aliquot vzas coagulated and the resulting polymer purified. Its intrinsic viscosity was 3.1 /g and analysis indicated 2 mole percent (1), 587 CIA and 40" nBA. Similar terpolyner latices were prepared from acrylates (2) and (3) (Scheme III). Another terpolymer latex made from (3), vinyl acetate, and 2-ethylhexyl acrylate contained 547 solids. Tliese latices and their compositions are summarized in the Table 1 and a sample experimental procedure is given in the experimental section. 

Substrates Sealed. Aqueous polymer solutions were coated on Estar base, which had been precoated with a subbing layer (5), to produce a 0.5-mil dry film thickness, then sealed to cellulose acetate, which had been precoated with another subbing layer (6). These subbing layers were vinyl terpolymers which were synthesized from acrylonitrile, vinyli-dene chloride, and acrylic acid. 

Comparing the phase diagrams of AC 540 modified DGEBA epoxy resin and hardener HHPA showed that the oxidized homopolymer with an acid functionality of 2.0 (AC 5120) was more miscible in epoxy resin and the RVP grafted AC 5120 had comparable miscibility as that of AC 5120. Similarly, ethylene acrylic acid-vinyl acetate terpolymer (AC 1450) was less miscible in epoxy resin compared to AC 5120 due to less chemical interaction with epoxy resin. Thus, the miscibility of the blends was reduced by the addition of HHPA to various blend systems.

Nowadays commercial mixtures of bitumens with uncured synthetic elastomers are produced, e.g. ethylene-propylene-diene terpolymers (EPDM), styrene-butadiene sequence copolymers (SBS), and ethylene-acrylic ester-acrylic acid terpolymers (AECM). Mixtures with some thermoplastics are also commercial products, e.g. polyethylene (PE), ethylene-propylene copolymers (EPM), alpha-olefinic copolymers, atactic polypropylene (aPP), and ethylene-vinyl acetate copolymers (EVA).
