Abstract
Improved performance and physical properties are obtainable from acrylamide-dialkylaminoalkyl acrylate polymers when the polymers are made by using a blend of at least about 15% dialkylaminoalkyl acrylate acid addition or quaternary ammonium salt with dialkylaminoalkyl methacrylate acid addition or quaternary ammonium salt.
Claims12
A high molecular weight cationic polyelectrolyte formed from acrylamide and cationic monomer characterised in that the polymer is a terpolymer of (a) dialkylaminoalkyl acrylate acid addition or quaternary ammonium salt with (b) dialkylaminoalkyl methacrylate acid addition or quaternary ammonium salt and (c) acrylamide, in which the molar ratio a:b is about 88:15 to about 5:95 and in which the molar amount of acrylamide based on the total molar amount of (A), (B) and (C) is 20 to 99%.
