ABSTRACT:
Vinylidene halide monomers are polymerized in water to form homo- and copolymer latices that are stable to mechanical agitation during polymerization and thereafter and to heat below 100.degree. C. are obtained when the vinylidene halide monomers are polymerized, optionally with other copolymerizable vinylidene monomers, in water in the presence of a catalyst or initiator and a neutralized polymer additive of an olefinically unsaturated carboxylic acid monomer containing at least one carboxylic acid group and a terminal methylene group, H.sub.2 C< copolymerized with at least one other copolymerizable vinylidene monomer containing a terminal vinylidene group CH.sub.2 <, said polymer additive having an acid number of greater than 50 to about 450 and a molecular weight of about 2,000 to about 50,000, used in amount of about one to thirty weight parts per one hundred weight parts of vinylidene monomers.
