摘要：
Provided are a method of preparing a vinyl chloride-based polymer composite, a vinyl chloride-based polymer composite, and a vinyl chloride-based polymer composite composition including the composite, the method including: a first step of performing bulk polymerization of vinyl chloride-based monomers; and a second step of recovering unreacted vinyl chloride-based monomers after the completion of the bulk polymerization and obtaining a vinyl chloride-based polymer composite, wherein polyvinyl alcohol is added in at least one step of the first step and the second step, and the polyvinyl alcohol is added in an amount of 0.003 parts by weight to 0.500 parts by weight based on a total of 100 parts by weight of the vinyl chloride-based monomers.
