Chiral polymers can be obtained in two different ways. The use of a chiral catalyst during polymerization can lead to helical structures, as observed in polysaccharides. The other synthesis path uses chiral monomers, which are polymerized to give a chiral polymer capable of folding to a supramolecular stmcture [20]. For application in HPLC, all of these polymers must be coated onto silica, since they are imable to withstand the high pressures encountered in HPLC. Currently, chiral stationary phases based on polyacrylates or polymethacrylates play only a minor role. Chirasphere (Merck) is derived from a silica material coated with poly(N-acryloyl-(S)-phenylalanine ethyl ester) and can be used for the separation of P-blockers in the normal-phase mode. The chiral polymethacrylates Chiralpak OP and Chiralpak OT (Daicel) are able to separate aromatic compounds into their enantiomers.

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%). 

Other examples of solvent effects in casting blends include epoxy resin/copoly-ester/tetrachloroethane polyethersulphone/poly(ethylene oxide)/cyclohexanone and mixtures of PVC with various polyacrylates in solvents such as THF One particular pair of polymers PVC/poly(ethyl acrylate) appear to be miscible but no suitable solvent has been found as yet. Homogeneous blends can only be prepared by in situ polymerisation though it is possible that miscibility is enhanced by small amounts of graft copolymer which is inevitably formed by this technique. 

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... 

Ethyl cyanoacrylate is a little less polar than methyl cyanoacrylate, and has the ability to wet plastic surfaces more readily, and is a better solvent for plastics. With this added ability to make intimate contact with the surface, the bonds on plastic are stronger with ethyl cyanoacrylate than with the methyl ester. This difference in performance gives rise to the adage that methyl is for metal and ethyl is for everything else. Sometimes this difference can be utilized in reverse to good advantage to avoid stress cracking on such sensitive plastics as polycarbonate and polyacrylate. 

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). 

Water can be used as the medium for a solvent-based adhesive when the polymeric material is water soluble. An example of such an adhesive would be a yarn-sizing formulation based on modified cellulose. Polyvinyl alcohol or polyacrylic acid. Generally, however, solvents are organic compounds, for example hydrocarbons (hexane, toluene), ketones (butan-2-one) and esters (ethyl acetate) see Solvent-based adhesives. 

Acrylic rubber can be emulsion- and suspension-polymerized from acrylic esters such as ethyl, butyl, and/or methoxyethyl acetate to produce polymers of ethyl acetate and copolymers of ethyl, butyl, and methoxyl acetate. Polyacrylate rubber, such as Acron from Cancarb Ltd., Alberta, Canada, possesses heat resistance and oil resistance between nitrile and silicone rubbers. Acrylic rubbers retain properties in the presence of hot oils and other automotive fluids, and resist softening or cracking when exposed to air up to 392°F (200°C). The copolymers retain flexibility down to -40°F (-40°C). Automotive seals and gaskets comprise a major market. These properties and inherent ozone resistance are largely due to the polymer s saturated backbone (see Table 3.13). 

It had been known that PMMA was compatible with PVC under some conditions, but contrary to earlier reports it has recently been found that a wide range of polyacrylates and polymethacrylates show compatibility with PVC. Such polymers are believed to be compatible due to a specific interaction between the carbonyl group in the ester and the hydrogen or halogen in the PVC. Similarly, it was known that poly(vinylidene fluoride) was compatible with PMMA and poly(ethyl methacrylate), it has now also been shown to be compatible with poly(vlnyl acetate), poly(vinyl methyl ketone), and polyacrylates. This work has also been extended to show the effect of tacticity on the compatibility of poly(ethyl methacrylate) where ail isomers are compatible but the isotactic form phase separates on heating."... 

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)... 

Kajtna and Sebenik described the synthesis of pressure-sensitive adhesives based on polyacrylates by suspension polymerization. The monomers used were 2-ethylhexyl acrylate (2-EHA) and ethyl acrylate (EA), and dibenzoyl peroxide (DBF) was used as initiator. Surface-active agents [modified ester of sulfocarboxylic acid (SCA) and ethoxylated oleyl alcohol (EOA)], chain transfer agent (w-dodecanethiol) (CTA) and suspension stabilizer [poly(vinyl alcohol) (PVA)] were also used. Various organically modified montmorillonites were used as fillers. It was observed that the kinetics of suspension polymerization were independent of the presence of the montmorillonite in the system, as shown in Figure 1.8.
