Abstract

PURPOSE: Polymerization of a vinyl monomer is conducted in an aqueous dispersion containing a salt of specific ethylenic hydrocarbon-maleic anhydride copolymer to prevent the adhesion of the polymer to the polymerizer and produce a polymer of reduced discoloration.
CONSTITUTION: The polymerization of a vinyl monomer is effected in an aqueous medium containing 0.1W10pts.wt., per 100pts. of the vinyl monomer, of an alkali metal salt of ethylenic hydrocarbon-maleic anhydride copolymer of the formula (R is 8W18C alkyl, alkenyl; m1, m2 are 1W5; M is K, Li, Na. n is 50W 100,000).
