Abstract
The present invention relates to a method of preparing a vinyl chloride-based polymer composite, which comprises dispersing a vinyl chloride-based monomer in water (Step 1); polymerizing the dispersed vinyl chloride-based monomer with an initiator to prepare a polymer slurry by (Step 2); and adding a phosphite to the polymer while drying the polymer slurry, to prepare a vinyl chloride-based polymer composite (Step 3), and a vinyl chloride-based polymer composite prepared by the method and a vinyl chloride-based polymer composite composition.
