ABSTRACT:
What is provided herein are cationic polymer compositions comprising a cationic polymer of strongly swellable, moderately crosslinked vinyl lactam, e.g. vinylpyrrolidone, and a quaternized amino alkyl acrylamido or acrylate, e.g. quaternized dimethylaminopropyl methacrylamide or dimethylaminoethyl methacrylate, optionally including a polymerizable carboxylic acid, e.g. acrylic acid or methacrylic acid, which includes about 0.1-0.8% of a crosslinking agent therein. These polymer compositions, in a concentration of 1-10% by weight in aqueous and non-aqueous medium, provide effective thickener action while imparting cationic characteristics to the resulting solution.
