Abstract
The present invention relates to a process for the formation of water soluble copolymers of acrylamide and alkyl poly(etheroxy)acrylate which are excellent viscosification agents, wherein the process includes the free radical copolymerization of acrylamide monomer and alkyl poly(etheroxy)acrylate monomer in an aqueous medium under nitrogen conditions in the presence of free radical initiator at a sufficient temperature and for a sufficient time to effect copolymerization.
