CA 2570312

The invention relates to the use of ether group-containing polymers as solubilizers, especially in cosmetics, drugs, food items, food supplements and feed stuff, ideally in the production of plant protectives. The inventive polymers are obtained by copolymerization of (A) optionally at least one ethylenically unsaturated monocarboxylic or dicarboxylic acid and/or at least one anhydride derived from a monocarboxylic or dicarboxylic acid, (B) at least one hydrophobic monomer which has aromatic functions or aliphatic functions or aromatic and aliphatic functions, (C) at least one allyl alcohol alkoxylate, (D) optionally other monoethylenically unsaturated monomers.

La présente invention concerne l'utilisation de polymères contenant des groupes éther en tant qu'agents de solubilisation, notamment dans le cas de cosmétiques, de médicaments, d'aliments, d'additifs alimentaire et d'aliments pour animaux, en particulier dans la fabrication d'agents phytoprotecteurs. Lesdits polymères peuvent être obtenus par copolymérisation (A) éventuellement d'au moins un acide monocarboxylique ou dicarboxylique à insaturation éthylénique et/ou d'au moins un anhydride dérivé de l'acide monocarboxylique ou dicarboxylique, (B) d'au moins un monomère hydrophobe présentant des fonctions aromatiques ou aliphatiques et des fonctions aromatiques et aliphatiques, (C) d'au moins un allylalcoolalkoxylate, et (D) éventuellement d'autres monomères à insaturation éthylénique.
