AQUEOUS EMULSION CONTAINING FINE PARTICLES OF CROSS-LINKED ALLYLIC COPOLYMER

摘要

A crosslinked allyl copolymer fine particle-containing aqueous emulsion having a polymerization degree of diallyl phthalate of at least 90% and an average particle size of at most 200 nm, which is obtained by emulsion-copolymerizing a monomer comprising (a) 10 to 40% by weight of diallyl phthalate, (b) 0.1 to 5% by weight of an α, β-unsaturated carboxylic acid and (c) a balance of an acrylate ester wherein the number of carbon atoms of an alcohol is from 1 to 8, has a good film formation property.
