ABSTRACT:
In a continuous bulk polymerization process of a styrene type copolymer which is a copolymer consisting of 60 to 95% by weight of an aromatic vinyl monomer and 40 to 5% by weight of maleic anhydride, a continuous bulk polymerization process of a styrene type copolymer characterized in that at the first stage, continuous bulk polymerization is carried out using a vertical agitation system polymerization apparatus to a conversion of 30 to 60% by continuously feeding a mixed monomer of the aromatic vinyl monomer and maleic anhydride having a feed composition ratio corresponding to the copolymer, and at the second stage, and at the third stage, if necessary, continuous bulk polymerization is carried out to a conversion of 60 to 95% using a horizontal apparatus for processing highly viscous substances, equipped with one or two rotary shafts having agitation blade frames or agitation blades impaled thereon, by continuously and dividedly feeding maleic anhydride from plural feed ports disposed on said apparatus for processing highly viscous substances.
