The present invention relates to the field of perfumery. More particularly, it concerns co-polymers, derived from a maleic anhydride derivative and a ethylenic derivative, comprising at least one β-oxy or β-thio carbonyl moiety capable of liberating an active molecule such as, for example, an α,β-unsaturated ketone, aldehyde or carboxylic ester. The present invention concerns also the use of polymers or co-polymers in perfumery as well as the perfuming compositions or perfumed articles comprising the invention's compounds.

[EN] The present invention relates to the field of perfumery. More particularly, it concerns co-polymers, derived from a maleic anhydride derivative and a ethylenic derivative, comprising at least one ß-oxy or ß-thio carbonyl moiety capable of liberating an active molecule such as, for example, an a,ß-unsaturated ketone, aldehyde or carboxylic ester. The present invention concerns also the use of polymers or co-polymers in perfumery as well as the perfuming compositions or perfumed articles comprising the invention's compounds. [FR] La présente invention concerne le domaine de la parfumerie. Plus particulièrement, elle concerne des copolymères issus d'un dérivé d'anhydre maléique et d'un dérivé éthylénique comprenant au moins une fraction b-oxy ou b-thio carbonyle capable de libérer une molécule active, telle qu'une cétone, un aldéhyde ou un ester carboxylique à insaturation a,b, par exemple. La présente invention concerne également l'utilisation de polymères ou de copolymères dans la parfumerie ainsi que les compositions de parfumerie ou les articles parfumés comprenant les composés de l'invention.
