Claims
- 1. A polyampholyte polymer, having an intrinsic viscosity of 0.05 to 4.5 dl/g in 1.0 M NaCl, prepared from 32.5 to 90 percent acrylic acid and/or methacrylic acid, 1.5 to 65 percent, by weight, of acrylamide and 0.5 to 25 percent, by weight, of dimethyldiallyl ammonium chloride and/or diethyldiallyl ammonium chloride.
- 2. The polyampholyte polymer of claim 1, wherein 1.5 to 10 percent, by weight, of dimethyldiallyl ammonium chloride and/or diethyldiallyl ammonium chloride is used.
- 3. The polyampholyte polymer of claim 1, wherein the polymer is a terpolymer of acrylic acid, acrylamide and dimethyldiallyl ammonium chloride.
