<p>Discrete, crosslinked vinylidene chloride polymer microgels, having a latex particle size of less than one micron and a gel content of 25 to 99 percent, such microgels being obtained by emulsion polymerizing(a) 50 to 95 parts by weight of vinylidene chloride, (b) 5 to 50 parts by weight of a copolymerizable ethylenically unsaturated comonomer, and (c) 0.1 to 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.</p> |
