摘要： One embodiment of the present invention provides a process, which includes: graft polymerizing a vinyl chloride monomer in suspension in the presence of a core-shell impact modifier; wherein the core-shell impact modifier includes: a core including polyvinyl chloride or vinyl chloride copolymers; and a shell including crosslinked alkyl (meth)acrylate homo- or copolymers. Another embodiment of the present invention provides a thermoplastic polyvinyl chloride molding composition modified with an elastomer-containing core-shell modifier, prepared by a process, which includes graft polymerizing a vinyl chloride monomer in suspension in the presence of a core-shell impact modifier; wherein the core-shell impact modifier includes a core including polyvinyl chloride or vinyl chloride copolymers; and a shell including crosslinked alkyl (meth)acrylate homo- or copolymers. Another embodiment of the present invention provides a plastic profile, which includes the above-noted composition. Another embodiment of the present invention provides an article selected from the group including window frame, pipe, film, siding and panel, which includes the above-noted composition. By the present invention, a thermoplastic polyvinyl chloride molding composition is obtained that has improved impact strength, corner strength and optical properties.
