Water absorbent styrene-acrylic acid copolymers |
摘要 |
Water absorbing, cross-linked acrylate resin copolymers are prepared by aqueous polymerization of (A) acrylic acid neutralized 70 to 100 mole percent for example with ammonia, and/or caustic alkali and/or an amine; with (B) styrene and/or methyl methacrylate in an amount of 1% to 25% based on the weight of acrylic acid or acrylate, and (C) acrylamide in a mole ratio of 70 to 100 mole percent (A) to 30:0 mole percent (C); and (D) a water miscible or a water soluble polyvinyl monomer in an amount of 0.001 to 0.3 weight percent based on the total weight of (A), (B), (C) and (D).
