Applications Radiotracer measurements, which combine high sensitivity and specificity with poor spatial resolution, have been used for migration testing. For example, studies have been made on HDPE, PP and HIPS to determine effects of manufacturing conditions on migration of AOs from plastic products into a test fat [443]. Labelled antioxidant was determined radio-analytically after 10 days at 40 °C. Acosta and Sas-tre [444] have used radioactive tracer methods for the determination of styrene ethyl acrylate in a styrene ethyl acrylate copolymer. 

The most widely used acrylic plastics are PMMA (Lucite) or copolymers of methyl methacrylate with small amounts (2 to 18%) of methyl or ethyl acrylate (Plexiglas). These commercial products, which are available as sheets and as molding powders, have a specific gravity of about 1.2, a heat deflection temperature of about 95 C, a refractive index of about 1.5, and a water absorption of 0.2%. PMMA is more resistant to impact than PS or glass, but its scratch resistance is inferior to that of glass,...

The ionic aggregates present in an ionomer act as physical crosslinks and drastically change the polymer properties. The blending of two ionomers enhances the compatibility via ion-ion interaction. The compatibilisation of polymer blends by specific ion-dipole and ion-ion interactions has recently received wide attention [93-96]. FT-IR spectroscopy is a powerful technique for investigating such specific interactions [97-99] in an ionic blend made from the acid form of sulfonated polystyrene and poly[(ethyl acrylate - CO (4, vinyl pyridine)]. Datta and co-workers [98] characterised blends of zinc oxide-neutralised maleated EPDM (m-EPDM) and zinc salt of an ethylene-methacrylic acid copolymer (Zn-EMA), wherein Zn-EMA content does not exceed 50% by weight. The blend behaves as an ionic thermoplastic elastomer (ITPE). Blends (Z0, Z5 and Z10) were prepared according to the following formulations [98] ... 

Another type of important linear polymers are the acrylates and methacrylates. In Figure 2.35, the repeating unit with two side groups from which these polymer types are derived is shown [195,197]. In Table 2.3, three examples of this type of polymers, specifically, poly (ethyl acrylate), which is applied in paints poly (methyl methacrylate), which is applied fundamentally as a construction material in place of glass and poly (ethyl methacrylate), which is applied as adhesives, are reported. 

Use of statistical copolymers in blends is usually predicated on the existence of a specific interaction between one of the comonomers in the copolymer and other ingredients in the mixture. Thus PVC is miscible with the ethyicne/ethyl acrylate/carbon monoxide copolymers [28]. The homogenizing effect here is a weak acid-base interaction between the carbonyl of the copolymer and the weakly... 

Specifically mentioned monomers include methyl acrylate, ethyl acrylate, propyl acrylate (all isomers), butyl acrylates (all isomers), 2-ethylhexyl acrylate, isobornyl acrylate, acrylic acid, benzyl acrylate, phenyl acrylate, acrylonitrile, glycidyl acrylate,... 

This is similar to PVC, but made from the monomer 1,1-dichloroethylene (CH, = CC I j. It has a specific gravity of 1.67-1.71 and a degree of polymerisation of over 200. The molecular weight of commercial polymers is about 20 0(X). It is often used in the form of a copolymer with vinyl chloride or ethyl acrylate to improve its properties. Coating formulations are plasticised with highly chlorinated aromatics, as common plasticisers are ineffective. 

There are multiple lUPAC names for ethyl acrylate, including ethyl propenoate and ethyl prop-2-enoate. When EINECS was developed, lUPAC naming conventions and specific names were not well established consequently, the name of this substance on EINECS is ethyl acrylate, with the EINECS listing 205-438-8. 

In this study, the specific polymers of interest are poly(2,2,2-tri iuoroethyl methacrylate), PTFEMA, poly(2,2,2-trifluoroethyl acrylate), PTFEA, and poly(hexa-fluoroisopropyl aaylate), PHFiPA, with the respective non-fiuorinated counterparts, poly(ethyl methacrylate), PEMA, poly(ethyl acrylate), PEA, and poly(isopropyl acrylate), PiPA. 

The use of monomethacrylates in anaerobic formulations was disclosed in a patent assigned to Loctite. Specifically mentioned were hydroxyethyl, hydroxypropyl, cyclohexyl, tetrahydrofurfuryl, dimethylaminoethyl, and glycidyl methacrylates and cyano-ethyl acrylate [148].
