Abstract
Styrene-type monomers are polymerized, or mixtures of styrene-type monomers and other vinyl type monomers and copolymerized, at 50.degree.-120.degree. C. using 1-10 wt%, based on the weight of the monomers, of an organic peroxide polymerization initiator whose decomposition temperature at 10 hours of halflife is 40.degree. C. to 70.degree. C. whereby colorless low molecular weight styrene series polymers are obtained at a high yield, using polymerization apparatus of simple structure.
