Method for the preparation of a polyvinyl chloride resin |
| abstract |
An improvement is proposed for decreasing triboelectric static charging of a polyvinyl chloride resin powder so as to improve the flowability of the powder and prevent a decrease in the bulk density of the powder due to static electricity. The improvement comprises adding to the aqueous polymerization mixture during the polymerization process a specified amount of an aqueous dispersion containing a salt of a long-chain carboxylic acid with a divalent metal and an ester of sorbitan with a long-chain carboxylic acid in a specified weight proportion and in a specified total concentration, at a point when conversion of the monomer to polymer is at least 70%. |
