ABSTRACT OF THE DISCLOSURE A homogeneous micellar free radical polymerization process for the formation of a terpolymer having the structure of: Image wherein S is selected from the group consisting of SO3M, phenyl SO3M, CONHC(CH3)2 CH2SO3M or COOM; M is selected from the group consisting of Groups IA, 1B, IIA and IIB of the Periodic Table of Elements, R1 is a C1 to C10 alkyl, cycloalkyl or aralkyl group, R2 is hydrogen or a C4 to C18lg alkyl, cycloalkyl or aralkyl group, x is about 10 to about 90 mole %, y is about 0.1 to about 60 mole %, and z is about 0.2 to about 10 mole % which comprises the steps of forming a mixture of an anionic surfactant, a nonionic surfactant, Image monomer, CH = Image monomer and CH2 = Image monomer under a nitrogen atmosphere; adding deoxygenated water to said mixture to form a homogeneous reaction solution; adding free radical initiator to said homogeneous reaction solution to initiate polymerization of said monomers; terpolymerizing said monomers at a sufficient temperature and for a sufficient period of time to form said terpolymer and without the formation of substantial amounts of particulates or phase separation occurring.
