Patent ID: 7479521

Claim:
A composition comprising: a water phase component; an oil phase component; at least one emulsifying agent of water-in-oil type; and at least one oil-in-water emulsifying agent, wherein said composition is one of (i) a self-invertible inverse latex comprising from about 20% to about 70% by weight of a product polymer and (ii) a self-invertible inverse microlatex comprising from about 10% to about 50% by weight of a product polymer, and said product polymer is selected from the group consisting of: copolymers of THAM and of 2-methyl-2-[(1-oxo-2-propenyl)amino]-1-propanesulfonic acid, wherein said acid is partially or completely salified in the sodium salt or ammonium salt form, copolymers of THAM and of AMPTAC, copolymers of THAM and of APTAC, copolymers of THAM and of DADMAC, copolymers of THAM and of 2-(dimethylamino)ethyl acrylate, copolymers of THAM and of 2-(dimethylamino)ethyl methacrylate, terpolymers of THAM, of AMPTAC, and of acrylamide, terpolymers of THAM, of AMPTAC, and of diacetone acrylamide, terpolymers of THAM, of APTAC, and of acrylamide, terpolymers of THAM, of DADMAC, and of diacetone acrylamide, terpolymers of THAM, of 2-(dimethylamino)ethyl acrylate, and of acrylamide, and terpolymers of THAM, of 2-(dimethylamino)ethyl methacrylate, and of diacetone acrylamide.
