发明名称 LARGE-SIZED VINYL CHLORIDE SEED, METHOD OF PREPARING THE SEED, VINYL CHLORIDE RESIN PREPARED USING THE SEED, AND METHOD OF PREPARING THE VINYL CHLORIDE RESIN
摘要 The present invention relates to a large-sized vinyl chloride seed with an average particle size of 0.65 to 1.5 μm, a vinyl chloride resin with improved low-viscosity properties, and preparation methods thereof. The preparation of the large-sized vinyl chloride seed includes adding a vinyl chloride monomer, an emulsifier, and a polymerization initiator to an aqueous medium; homogenizing the mixed solution using a rotor-stator type homogenizer; and subjecting the resultant monomer droplets to a polymerization reaction.
