摘要： Disclosed are inverse emulsion wherein the weight ratio between the aqueous phase and the organic phase is from 4:1 to 2:1 and containing from 20 to 70% by weight of an acrylic polymer comprising monomeric units deriving from: i) 2-acrylamido-2-methylpropanesulfonic acid; ii) at least one cationic acrylic monomer of formula I:

I wherein R 1 is hydrogen or methyl; R 2 , R 3 , R 4 are, one independently of the others, hydrogen or C 1 -C 4 alkyl; Y is NH or O; A is a C 1 -C 6 alkylene; X is chloride; iii) acrylic or methacrylic acid; iv) at least one polyfunctional monomer, the inverse emulsion being characterized by the fact that in the polymer the monomeric units deriving from 2-acrylamido-2-methylpropanesulfonic acid represent from 1% to 29% molar of the total monomers i), ii) and iii).
