Abstract:
1. Polymeric thickener composition comprising at least one Water-swellable cross-linked copolymer derived from polymerization of a mixture having a pH of 3 to 5 consisting of: (a) acrylamide, (b) an acrylamidoalkylsulfonic acid and/or a salt thereof; and (c) an amine-based polyfunctional crosslinking agent comprising at least three allylic functions, and a chain transfer agent, wherein the polyfunctional crosslinking agent is triallylamine and is contained in the polymerization mixture in an amount of more than 2 millimoles per mole of total monomer units and up to 10 millimoles per mole of total monomer units.
