| titleOfInvention | Suspension polymerization of vinyl chloride resin |
| abstract | (57) [abstract] (with correction) [PROBLEMS] Resin scale does not adhere to the inner wall of a joiner, the resulting vinyl chloride resin has a sharp particle size distribution and a high bulk specific gravity, and almost a skin layer is formed on the particle surface. A suspension polymerization method of a vinyl chloride resin having no parts and excellent moldability. The present invention relates to a method for subjecting a vinyl chloride monomer to suspension polymerization in an aqueous medium in the presence of an oil-soluble polymerization initiator, In the reaction system, the degree of saponification is 60 to 80 mol%, the average degree of polymerization is 450 to 600, and the viscosity (water / methanol = (Viscosity of 4% by weight solution with respect to 1/1 (weight ratio) solvent) Is 3 to 10 cP, partially saponified polyvinyl acetate (a), A sorbitan higher fatty acid ester having an HLB value of 3 to 10, at least one emulsifier (b) among anionic emulsifiers, a higher fatty acid (c) of 8 to 25, and 0.1 wt. % Aqueous solution having a Brookfield viscosity of 10 to 200 cP is added. |
