Aqueous, anionic, acrylic polymer compositions comprising a copolymer of an alkyl acrylate, an alkyl methacrylate and one or more acrylate acids or salts thereof are disclosed. By controlling the particle size of the copolymer and introducing a surfactant, enhanced freeze-thaw stability can be obtained with the polymer compositions of the present invention. The polymer compositions are compatible in all-aqueous hairspray compositions, as well as those which contain up to about 80 weight percent volatile organic compounds, or more.
本发明公开了由丙烯酸烷基酯、甲基丙烯酸烷基酯和一种或多种丙烯酸酯酸或其盐的共聚物组成的水性阴离子丙烯酸聚合物组合物。通过控制共聚物的粒度和引入表面活性剂,本发明的聚合物组合物可获得更高的冻融稳定性。本发明的聚合物组合物可用于全水性发胶组合物,也可用于挥发性有机化合物含量高达约 80% 或更高的发胶组合物。
