| 摘要 |
<p>This invention relates to polymers which comprise the reaction product of: (A) about 1-99.8 weight percent of one or more nonionic, cationic, anionic or amphoteric monomers; (B) about 0-98.8 weight percent of one or more monoethylenically unsaturated monomers different from (A); (C) about 0.1-98.8 weight percent of one or more monoethylenically unsaturated macromonomers different from (A) and (B); (D) about 0.1-98.8 weight percent of one or more monoethylenically unsaturated macromonomers different from (A), (B) and (C); (E) about 0-20 weight percent or greater of one or more polyethylenically unsaturated monomers different from (A), (B), (C) and (D); and (F) about 0-25 weight percent or greater of one or more acrylates and/or methacrylates derived.from a strong acid or a salt of a strong acid different from components (A), (B), (C), (D) and (E). The polymers of this invention are especially useful as thickeners and dispersants for aqueous systems, especially latex paints.</p> |
