    Abstract: The invention relates to a method for producing a polymer in water, comprising the preparation of an emulsion comprising a HASE-type copolymer and a mixture of a monomer comprising at least one polymerisable olefinic unsaturation and a radical-generating compound, followed by the polymerisation of the emulsified monomer by heating to a temperature higher than the temperature required for the polymerisation reaction. The invention also relates to the polymer produced in this way and to the use thereof.

    Abstract: (EN) The invention relates to the field involved in the production of aqueous compositions comprising rheology modifying agents, in particular the production of aqueous detergent or cosmetic compositions having improved, thickening and clarity properties, as well as good suspension properties. In particular, the invention relates to a rheology modifying agent which is a copolymer obtained by means of polymerisation of at least one crosslinking monomer with at least one anionic monomer comprising at least one polymerisable ethylenic unsaturation and at least one hydrophobic non-ionic monomer comprising at least one polymerisable ethylenic unsaturation.

    Abstract: Anti-UV cosmetic compositions in the form of an emulsion may include an emulsifying polymer which is prepared by polymerizing an anionic monomer and a C1-C7 ester of an unsaturated carboxylic acid. Such anti-UV cosmetic compositions may be prepared in the absence of a surfactant. The preparation and use of such anti-UV cosmetic compositions may provide anti-UV cosmetic composition having dual protection for the skin: protection against UV rays and limiting the penetration of UV filters into the skin.
