| 摘要 |
The invention provides vinylidene halide copolymer latices comprises of (A) vinylidene halide as the principle copolymerized comonomer; (B) from about 0.2 to about 5 percent by weight of an ethylenically unsaturated sulfated monomer represented by the structural formula: <IMAGE> wherein R is hydrogen or alkyl, R' is a hydrocarbylene group, N is a positive integer and M is a cation; (C) from about 0.5 to about 25 percent by weight of a hydroxyalkyl ester of an alpha, beta-ethylenically unsaturated carboxylic acid; and up to 40 percent by weight of an ethylenically unsaturated monomer other than comonomers (A)-(C). The latices coating attributes may be selectively altered for a desired end-usage by varying the copolymer composition. Latices which may be converted to vinylidene chloride coatings of superior anti-blocking and/or oxygen barrier resistance are provided.
