Abstract: A continuous mass polymerization process for making an extrusion grade ABS resin having desirable properties and suitable for making refrigerator liners is disclosed. The process comprise charging a reaction mixture into a first in a series of reactors under conditions promoting polymerization, the mixture comprising diene rubber, a mixture of monomers, inert solvent and a chemical initiator to form a reaction mixture. The mixture is then transferred into a subsequent reactor operating at a temperature of 130 to 155° C. with no addition of chemical initiator and the resulting product is then devolatilized. The ABS thus produced contains about 10 to 16 pbw of dispersed rubber particles having an average particle diameter of 0.3 to 0.7 microns.
