Abstract: A process for producing rubber modified polymers having an increased rubber phase volume, including feeding a vinyl aromatic monomer and an elastomer to a polymerization reactor to form a reaction mixture, polymerizing the reaction mixture, combining a copolymer to the polymerized reaction mixture to form a combined mixture, subjecting the combined mixture to further polymerization, and obtaining a rubber modified polymer product from the further polymerization.
