Methyl arid ethyl acrylates are toxic enough to require a hazardous shipping label, bur butyl-, isobutyl-, and 2-ethyl hexyl-acrylates have high enough flash points to be considered safe. 

In a separate investigation by Kent et al. (3) latex compositions containing poly(methyl methacrylate-co-hexyl acrylate) were prepared containing the ultraviolet absorber monomer Norbloc 7966. 

Several ester monomers have also been studied. In methanol solution, methyl acrylate (16,21), ethyl acrylate (21,54), 2-ethyl hexyl acrylate (55), allyl acrylate (44), glycidyl acrylate (56,57) usually in methanol solution, have been extensively studied. Methyl methacrylate (19, 21, 28, 30, 36, 39, 58) in diversified media composition, has been successfully grafted on polyamides. Vinyl acetate is reported also for grafting on polyamide backbone (19, 28, 35, 58), as well as n-butyl maleate in methanol solution (55). Diallyl maleate as cross-linking agent for polyamide chains is reported (44). Other less usual ester monomers have been mentioned in the literature to form grafts (41,59,60). 

On the other hand, chemicals might be chosen as agents for generation of active centers in the polymeric backbone and grafting of monomer in the vapor phase. Ammonium persulfate and styrene (189), acrylic acid (190), butyl acrylate (191), potassium persulfate and n-butyl maleate or 2-ethyl hexyl acrylate (55,134) and ammonium ceric nitrate and methacrylic add (192) are examples of this method. Benzoyl peroxide deposited on polycaprolactam fibers initiates the grafting of styrene in vapor phase (193). 

Steric stabilization of poly(2-ethyl hexyl acrylate) (PEHA) emulsions in C02 was studied with static and dynamic light scattering (DLS) (O Neill et al., 1997 Yates et al., 1997). These emulsions were stabilized with PFOA-based surfactants. Figure 8.9 shows the average droplet size (hydrodynamic radius) measured by DLS for a liquid PEHA emulsion in C02 stabilized...

The mechanism of radiation vulcanisation of NR with 2-ethyl hexyl acrylate (EHA) was examined by 13C NMR [46]. All peaks in spectrum due to the acrylate decrease in intensities and broaden with increasing radiation dose. Using the solid-state CP technique, all peaks corresponding to EHA and NR were observed. The olefin peak at 129 ppm in the acrylate was absent, however, indicating that all the EHA had polymerised. 

The author notes that his results are consistent with those of Stam-berger (27) who worked with a styrene-ethyl hexyl acrylate-acrylic acid emulsion terpolymer. At pH 8, the emulsion was stable to liquid shear, whereas at pH 3, it was unstable. There was little difference in zeta potential of the latex at the two pH values.

A mixture consisting of water (190 g), ethyl alcohol (10 g), hexadecyl acrylate (70 g), hexyl acrylate (25 g), methyacrylic acid (5g), 3.2% sodium dodecyl sulfate, and ammonium dodecyl benzene sulfonate (5 g) was charged into a reactor and degassed for 30 minutes. Potassium persulfate (0.4 g) was then added, and the polymerization was conducted for 4 hours at 70°C under nitrogen. After the polymer was isolated, a sharp DSC endotherm was observed at 22.5°C.

To reduce the glass transition temperature of the rubber to improve the low-temperature properties of the ASA products. Especially preferred is ethyl-hexyl acrylate [59,60]. A further method is the incorporation of silicone rubber into the ASA particles [55,61-65]. 

The structure of the liquid- liquid interfadal layer depends on the difference in polarity between the two liquids (Kaeble, 1971). Asymmetric molecules of some liquids display a molecular orientation on the interface which is indicative of their structure. Thus, interfacial tension at the octane-water interlace is SO.S nm/m whereas at the octanol-water interne it is only 8.8 nm/m. Reduction of inter dal tension in the latter case points to the orientation of octanol hydroxyl groups toward water, in other words to the structure and polarity of the interfadal layer. Because of such an orientation, the stimulus for adsorption of other asymmetric molecules on the interface is decreased. A similar pattern is typical of the homologous series of lower attcy] acrylates at the interface with water the carbonyl groups of their asymmetrical molecules are oriented toward water this orientation is more eSective the higher the polarization of the carbonyl, i.e the smaller the alkyl. Interfadal tension decreases in the same order from 27.2 nm/m for hexyl acrylate (Yeliseyeva et at, 1978) to 8 nm/m for methyl acrylate (datum from our laboratory by A, Vasilenko).
