Polymers are disclosed which comprise: (A) about 1-99.9 weight percent of one or more alpha, beta-monoethylenically unsaturated carboxylic acids, typically methacrylic acids; (B) about 0-98.9 weight percent of one or more monoethylenically unsaturated monomers, typically ethyl acrylate; (C) about 0.1-99 weight percent of one or more monoethylenically unsaturated macromonomers, and (D) about 0-20 weight percent or greater of one or more polyethylenically unsaturated monomers. These polymers can be solubilized in water with the aid of an alkali, like ammonium hydroxide. When the polymers are added to latex paints and neutralized, the viscosity of the paint is increased, brush drag is increased, and the paint rheology is otherwise improved.
揭示了一种聚合物,其中包括:(A)约1-99.9重量%的一种或多种α,β-单乙烯不饱和羧酸,通常为甲基丙烯酸;(B)约0-98.9重量%的一种或多种单乙烯不饱和单体,通常为乙酸乙酯;(C)约0.1-99重量%的一种或多种单乙烯不饱和的大分子单体,以及(D)约0-20重量%或更多的一种或多种多乙烯不饱和单体。这些聚合物可以在碱的帮助下溶于水中,例如氢氧化铵。当将这些聚合物添加到乳胶漆中并中和时,可以增加漆的粘度,增加刷涂阻力,并改善漆的流变学性质。
