Abstract
A vinyl-containing copolymer is copolymerized from (a) first compound, (b) second compound, and (c) third compound. (a) First compound is an aromatic compound having a single vinyl group. (b) Second compound is polybutadiene or polybutadiene-styrene having side vinyl groups. (c) Third compound is an acrylate compound. The vinyl-containing copolymer includes 0.003 mol/g to 0.010 mol/g of benzene ring, 0.0005 mol/g to 0.008 mol/g of vinyl group, and 1.2*10−5 mol/g to 2.4*10−4 mol/g of ester group.
