Polymer conjugates for a controlled release of active molecules
摘要:
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.
