ABSTRACT:
An impact resistant styrene resin is prepared by the continuous bulk polymerization of a styrene monomer in the presence of a second component having a 5 wt % styrene solution viscosity which may be polybutadiene, styrene-butadiene copolymerization rubber, or mixtures thereof. Preliminary polymerization is carried out in a reactor having a dynamic mixing structure and which is integrated between and connected to the material feed line and the initial-stage polymerization line.
