Abstract
A continuous mass polymerization process for preparing rubber reinforced styrenic copolymers comprising forming a solution in an inert solvent of a styrenic polymer matrix and a monomer material capable of polymerizing to form a cross-linked rubbery polmyer, continuously charging the solution into a polymerization reactor and subjecting the solution to mass polymerization conditions whereby there is formed in situ a cross-linked rubbery polymer dispersed in the styrenic polymer matrix, continuously withdrawing the reaction mixture from the polymerization reactor and recovering the resulting rubber reinforced styrenic copolymer.
