Claims
- 1. A coating latex containing discrete, cross-linked vinylidene chloride polymer microgels, said latex comprising the product obtained by emulsion polymerizing (a) about 88 to about 92 parts by weight of vinylidene chloride; (b) about 6 to about 12 parts by weight of methyl acrylate or methyl methacrylate; (c) about 1 to about 5 parts by weight of a copolymerizable crosslinking polyfunctional comonomer; and (d) about 1 to about 10 parts by weight of a comonomer selected from the group consisting of acrylic acid, methacrylic acid, itaconic acid, and fumaric acid, said microgels having a particle size of about 0.1 to about 0.5 micron, a gel content of about 1 to about 50 percent, and a second order transition temperature less than about 30.degree. C.
- 2. The latex of claim 1 obtained by emulsion polymerizing (a) about 90 parts by weight of vinylidene chloride, (b) about 10 parts by weight of methyl methacrylate, (c) about 2 parts by weight of 1,3-butylene glycol diacrylate, and (d) about 4 parts by weight of acrylic acid.
- 3. A coating latex containing discrete, cross-linked vinylidene chloride polymer microgels, said latex comprising the product obtained by emulsion polymerizing (a) about 90 to about 94 parts by weight of vinylidene chloride, (b) about 6 to about 10 parts by weight of methyl acrylate or methyl methacrylate, and (c) about 1 to about 5 parts by weight of a copolymerizable crosslinking polyfunctional comonomer, said microgels having a particle size of about 0.1 to about 0.5 micron, a gel content of about 1 to about 50 percent, and a second order transition temperature less than about 30.degree. C.
- 4. The latex of claim 3 obtained by emulsion polymerizing (a) about 92 parts by weight of vinylidene chloride, (b) about 8 parts by weight of methyl methacrylate, and (c) about 2 parts by weight of 1,3-butylene glycol diacrylate.
