US Patent 8211414 Water soluble polymer complexes with surfactants

A complex including a polymer and a surfactant formed by polymerizing a monomer mixture containing:(A) acid functional monomers at least partially neutralized with one or more amines according to one or more of formulas (I) through (IV):R1—NR2R3  (I)R1—N+R2R3R7X−  (II)R4—C(O)—NR5—R6—NR2R3  (III)R4—C(O)—NR5—R6—N+R2R3R7X−  (IV)wherein R1 and R4 are independently a C8-C24 group; R2, R3 and R5 are independently H or a C1-C6 group, or where R2 and R3 combine to form an anelled ring of from 4 to 12 carbon atoms in length optionally containing hetero atoms; R6 is C1-C24 group, R7 is H or a C1-C12 group, and X is a halide, a sulfate or a sulfonate;(B) one or more cationic monomers; and optionally(C) one or more other monomers.
