A homogeneous free radical copolymerization process for the formation of a copolymer of acrylamide and a cationic hydrogen-bonding alkoxypropyl which comprises the steps of: (a) forming a mixture of monomer and the acrylamide-monomer under a nitrogen atmosphere; (b) adding deoxygenated water to said mixture to form a homogeneous reaction solution; (c) adding a free radical initiator to said homogeneous reaction solution to initiate polymerization of said acrylamide monomer and said cationic hydrogen-bonding alkoxypropyl monomer; and (d) copolymerizing said acrylamide monomer and said monomer at a sufficient temperature and for a sufficient period of time to form said copolymer of acrylamide monomer and without the formation of substantial amounts of particulates or phase separation occurring, said copolymer having an intrinsic viscosity of about 1 to about 10 dl/g. said copolymer having the formula: <IMAGE> wherein n is 6 to 22 straight chained or branched alkyl or cycloalkyl group. X is about 90 to about 99.9 mole % and y is about 0.1 to about 10.0 mole %.
