Case No. 08-12-0421 A PROCESS FOR POLYMERIZING TERPOLYMER POLYBLENDS HAVING LOW SURFACE GLOSS ABSTRACT OF THE INVENTION This invention relates to a process for pre- paring terpolymer polyblends having low gloss in ex- truded profiles wherein rubber particles contained in an aqueous latex are grafted with alkenyl aromatic, alkenyl nitrile and conjugated diolefin monomers to form a grafted rubber phase dispersed in a matrix phase of said monomers, at least a portion of said rubber particles becoming associated with said ter- polymers as a gel fraction in said polyblend reducing the gloss of formed polyblend articles. The invention also relates to a composition prepared by said process.
