    摘要： A comb copolymer consisting of a polymer backbone on which lateral macromonomer segments are grafted,
    characterised in that said polymer backbone consists: Of more than 55% and up to 90% molar of monomeric units from 2-methyl-2-[(1-oxo-2-propenyl)-amino]-1 -propanesulphonic acid (hereinafter referred to as ATBS), Of between 1% and 20 % molar, and more specifically of between 4% and 15% molar, either of monomeric units from a cationic monomer or of monomeric units from a monomer of formula (I): CH
    2 =C(R1)-C(=0)-Y-(CH2)m-N(R2)(R3) in which m represents a number of between 1 and 4, Y represents O or NH, R-i represents a hydrogen atom or a methyl radical, R2 and R3, identical or different, represent a methyl radical or an ethyl radical; - Optionally of 0.005% molar to 1% of monomeric units from at least one cross-linking monomer comprising at least two carbon-carbon double bonds, and in that said lateral macromonomer segments are, for 100% molar constituting said comb copolymer, derived from the polymerisation of 9% to 30% molar of N-alkyl acrylamide or Ν,Ν-dialkyl acrylamide of formula (II): CH2=C(R4)-C(=0)-N(R5)(R6), in which R4 represents a hydrogen atom or a methyl radical and R5 and R6 represent, independent of each other, a hydrogen atom or an alkyl radical comprising 1 to 3 carbon atoms, it being understood that at least one of the R5 or R6 radicals does not represent a hydrogen atom, the method for the preparation and the use thereof as a thickener in cosmetics.

    摘要： A method for preparing a comb copolymer, of which the backbone consists, for 0% molar: - Of 50% to 100% molar of monomeric units from 2-acrylamido-2-methyl-propanesulphonic acid, and up to 50% of optional backbone monomeric units, on which lateral poly(N-alkyl acrylamide) or poly(N,N-dialkyl acrylamide) segments are grafted, said method comprising the following successive steps: -A step (a) of reacting a compound of formula (II): CH
    2 =C(R2)-C(=O)-N(R3)(R4) (II), with a chain-limiting compound of formula (IIIa): HS-R1-NH2 (IIIa) or of formula (IIIb): HS-R1-C(=O)-OH (IIIb), in order to obtain a poly(N-alkyl acrylamide) or poly(N,N-dialkyl acrylamide) telomer, of formula (Ia): H2N-R1-S-{CH2-C(R2)[C(=O)N(R3)(R4)]-}n-H (Ia) or of formula (Ib): HO-C(=O)-R1-S-{CH2-C(R2)[C(=O)N(R3)(R4)]-}n-H (Ib) formula (IIIa) or (IIIb) in which n represents a whole number greater than or equal to 2 and less than or equal to 100; -A step (c) of reacting the telomer of formula (Ia) or of formula (Ib) in tert-butanol with glycidyl methacrylate (IV) to obtain a solution of the macromonomer of formula (Va): CH2=C(R5)-C(=O)-NH-R1-Z-{CH2-C(R2)[C(=O)N(R3)(R4)]-}n-H (Va) or of formula (Vb); CH2=C(R5)-C(=O)-O-(C=O)-R1-Z-{CH2-C(R2)[C(=O)N(R3)(R4)]-}n-H (Vb); -A step (e) of copolymerising the macromonomer of formula (Va) or of formula (Vb) in tert-butanol with the ammonium salt of 2-acrylamido-2-methyl-propanesulphonic acid, and, if applicable, with the optional monomer or monomers in the desired molar proportions; novel comb copolymers.

    摘要： The invention relates to a composition in the form of a positive latex comprising: a) between 50 wt. % and 80 wt. % of at least one cross-linked, branched, or linear organic polymer (P), b) between 5 wt. % and 10 wt. % of a water-in-oil (W/O) emulsifying system (S1), c) between 5 wt. % and 45 wt. % of at least one oil, and d) between 0 wt. % and 5 wt. % of water. The inventive composition is characterised in that between 0.01 mol. % and 10 mol. % of the monomeric patterns of said monomer P comprise at least one neutral monomer of formula (I): C(R1)(R3)=C(R2)-C(=0)-0-(CH2-CH2-O)n-R4 (I) wherein the radicals R1, R2 and R3, which are the same or different, independently represent a hydrogen atom or a linear or branched alkyl radical comprising between 1 and 4 carbon atoms, the radical R4 represents a linear or branched, saturated or unsaturated, aliphatic radical comprising between 6 and 30 carbon atoms, and n represents a number between 1 and 50. The invention also relates to a method for the production of said composition and the use of the same.
