Patent ID: 8148433

Claim:
A composition in the form of an inverse latex comprising: a) from 50% by weight to 80% of at least one linear, branched or crosslinked organic polymer (P), b) from 5% by weight to 10% of an emulsifying system (S 1 ) which is a water-in-oil (W/O) emulsion, c) from 5% by weight to 45% by weight of at least one oil, and d) from 0% to 5% of water, wherein from 0.01% to 10% in molar proportions of monomer units of said polymer P include at least one neutral monomer of formula (I′): CH 2 ═CH—C(=0)-0-(CH 2 —CH 2 —O) n′ —R′ 4 (I′) radical R′ 4 is an aliphatic radical selected from the group consisting of octyl, decyl, dodecyl, tetradecyl, hexadecyl, octadecyl, eicosyl, docosyl and tetracosyl radicals, and n′ is a number between 4 and 25; or said polymer (P) is a copolymer in which each of the monomers, which are different from formula (I′), is independently of each other selected from the group consisting of a monomer containing a partially or totally salified strong acid function, a monomer containing a partially or totally salified weak acid function and from neutral a monomer.
