Abstract
Discrete, crosslinked vinylidene chloride polymer microgels, having a latex particle size of less than 1 micron and a gel content of about 1 to 99 percent, such microgels being obtained by emulsion polymerizing (a) about 50 to about 95 parts by weight of vinylidene chloride, (b) about 5 to about 50 parts by weight of a copolymerizable ethylenically unsaturated comonomer, and (c) about 0.1 to about 10 parts by weight of a copolymerizable crosslinking polyfunctional comonomer. Such microgels have been found to have wide applicability as additives for synthetic foams and fibers, and for the preparation of improved coatings, films, and redispersible latexes.
