Abstract:
1. A composition in the form of an inverse latex comprising, for 100% of its mass: a) from 10% by mass to 80% by mass of a linear, branched or crosslinked polymer (P) of 2-methyl-2-[(1-oxo-2-propenyl)amino]-1-propanesulfonic acid (also known as 2-acrylamido-2-methylpropanesulfonic acid) which is partially or totally salified, and optionally one or more monomers chosen from acrylic acid, methacrylic acid, itaconic acid, maleic acid or 3-methyl-3-[(1-oxo-2-propenyl)amino]butanoic acid, said monomers being free, partially salified or totally salified, acrylamide, methacrylamide, diacetone acrylamide, N,N-dimethylacrylamide, N-isopropyl-acrylamide, N-[2-hydroxy-1,1-bis(hydroxymethyl)-ethyl]propenamide [or tris(hydroxymethyl)acrylamido-methane or N-tris(hydroxymethyl)methylacrylamide also known as THAM], (2-hydroxyethyl) acrylate, (2,3-dihydroxypropyl) acrylate, (2-hydroxyethyl) methacrylate, (2,3-dihydroxypropyl) methacrylate, an ethoxylated derivative, of molecular weight between 400 and 1000, of each of these esters or vinylpyrrolidone; 2,N,N,N-tetramethyl-2-[(1-oxo-2-propenyl)amino]propanammonium chloride, bromide or iodide, 2,N,N-trimethyl-2-[(1-oxo-2-propenyl)amino]-propanammonium chloride, bromide or iodide, N,N,N-trimethyl-2-[(1-oxo-2-propenyl)oxy]ethanammonium chloride, bromide or iodide, N,N,N-trimethyl-3-[(1-oxo-2-propenyl)oxy]propanammonium chloride, bromide or iodide, N,N,N-trimethyl-2-[(1-oxo-2-propenyl)-amino]propanammonium chloride, bromide or iodide, or diallyldimethylammonium chloride, bromide or iodide; b) from 5% by mass to 10% by mass of an emulsifying system (S c) from 1% by mass to 50% by mass of water, d) from 5% by mass to 50% by mass of at least one compound chosen from the compounds of formula (I): in which R
