| 摘要 |
Aqueous polymer emulsions suitable for preparation of high wet adhesion latex paints comprise an emulsified film-forming copolymer of a first, hard monomer such as styrene, a second, soft monomer such as butyl acrylate, a wet adhesion monomer and an acidic copolymerizable dry-adhesion promoter, the copolymer having a minimum film forming temperature of about 25.degree.C. The emulsions are prepared by free radical polymerizations, in latex, by procedures specially adapted to avoid mutual neutralization of the monomers prior to polymerization. |
