发明名称	MANUFACTURING METHOD OF PVC POLYMER AND PVC COPOLYMER USING SUSPENSION POLYMERIZATION SEED
摘要	PURPOSE: A method for preparing a PVC polymer using a suspension polymerization seed is provided to improve polymerization productivity by reducing polymerization time and to block fish eye generated by non-dissolved particles of a reactant. CONSTITUTION: A method for preparing a PVC polymer using a suspension polymerization seed comprises the steps of: preparing a vinyl chloride polymer which is suspension polymerization seeds with 5 ~ 20% conversion ratio using a prepolymerization reactor; transferring the vinyl chloride polymer to the polymerization reactor and performing suspension polymerization reaction with a vinyl chloride monomer in the presence of protective colloid formations and polymerization initiators.
