摘要： Novel styrene-based polymers and a process for efficient production thereof are disclosed. The styrene-based polymers have a branching nucleus represented by the general formula: R(S).sub.k or R(A-S).sub.k (wherein all the symbols are as defined in the appended claims), and have a sulfur content of 6 to 550 ppm, a weight average molecular weight of 450,000 to 1,300,000, and a weight average molecular weight/number average molecular weight (Mw/Mn) ratio of 2:1 to 15:1. The styrene-based polymers are greatly improved in impact resistance while maintaining sufficiently high fluidity and moldability and thus when injection or extrusion molded, can provide moldings having an excellent mechanical strength.
