Document Type and Number:
WIPO Patent Application WO/2021/225394
Kind Code:
A1
Abstract:
The present invention relates to a method for preparing a vinyl chloride polymer composite, a vinyl chloride polymer composite, and a vinyl chloride polymer composite composition comprising same, the method comprising: a first step of mass polymerizing a vinyl chloride monomer; and a second step of recovering an unreacted vinyl chloride monomer and obtaining a vinyl chloride polymer composite after the mass polymerization, wherein polyvinyl alcohol is added in the first step and/or the second step, and the polyvinyl alcohol is added in an amount of 0.003 to 0.500 parts by weight relative to 100 parts by weight of the total vinyl chloride monomer.
