摘要： This invention offers a functional vinyl halide polymer that has excellent processing properties for the end-user processing without any extra processing aid. This functional vinyl halide polymer has good fusion, lubrication and melting strength in processing. The finished products show a good characterization of high transparence, low air-mark and low flow-mark. The functional vinyl halide polymer is produced by a solution, bulk or suspension polymerization. Vinyl halide or a monomer mixture comprising mainly vinyl halide is polymerized in an aqueous medium in the presence of an acrylic copolymer latex/powder to obtain the functional vinyl halide polymer. The functional vinyl halide polymer manufacturing process mainly comprises the copolymerization or graft-polymerization of: (A) 90.0 wt %˜99.9 wt % based on the total composition of the vinyl halide or the monomer mixture, and (B) 10.0 wt %˜0.1 wt % based on the total composition of the alkyl acrylate monomers or the acrylic polymer latex/powder, wherein the former can be added stepwisely or all in one time and the later can be charged continuously into reactor during polymerization or charged into a reactor before polymerization.
