Abstract
A process for controlling the surface gloss of a molded composition of: (a) a polyvinyl chloride resin and (b) a graft copolymer comprising a discontinuous poly(alkyl(meth)acrylate) rubber phase and a rigid thermoplastic phase, wherein at least a portion of rigid thermoplastic phase is chemically grafted to the poly(alkyl(meth)acrylate) rubber phase, by regulating the cross-link density and thus the swell index of the rubber phase in the graft copolymer to at least about 8 to vary the surface gloss after extrusion.
