반응 단계

The procedure described in Example 1(A) was repeated, except that the diallyl phthalate crosslinking monomer was replaced by the aromatic diacrylate monomer available commercially as "Photomer" 4028 (Registered Trade Mark of Diamond Shamrock Co.) and which is believed to be essentially the diacrylate of bisphenol A. The amounts of the monomers were adjusted to give a polymer composition of ethyl acrylate 61.5%, methyl methacrylate 28%, 2-hydroxyethyl acrylate 10%, "Photomer" 4028 0.5%, and the amount of copolymer stabiliser solution in the main feed was increased from 294.9 parts to 368.6 parts. The final dispersion had a non-volatile content of 61.6%, a high-shear viscosity of 0.8 poise and a particle size ("Nanosizer" determination) of 0.25 μm. The gel content of the disperse phase was 89%. When the dispersion was applied to glass and allowed to dry, a good clear, flexible film was obtained; its extensibility was in excess of 1000%.
