Abstract
A prepolymer, which is prepared by subjecting an unsaturated bond-containing compound and a bis(vinylphenyl) compound monomer or a polymer thereof to a prepolymerization reaction, is provided. The bis(vinylphenyl) compound contains between 80% and 99% of para-para vinyl groups and has a monomer content of between 80% and 100%. Moreover, a resin composition comprising the prepolymer and an additive, a method of preparing the prepolymer, and an article made from the resin composition are also provided.
