A process is described for obtaining a chemical blend of a polyolefin with a poly(hydroxy carboxylic acid) by mixing poly(hydroxy carboxylic acid) with at least one polyolefin in the presence of a compatibilising compound having at least one polymerisable double bond and at least one electrophilic functional group. The invention also relates to the chemical blend obtainable according to this process, as well as the use of the compatibilising compound to obtain chemical blends of polyolefin with poly(hydroxy carboxylic acid).
La présente invention concerne un procédé permettant d'obtenir un mélange chimique associant une polyoléfine et un poly(acide hydroxycarboxylique) en mélangeant le poly(acide hydroxycarboxylique) avec au moins une polyoléfine en présence d'un composé compatibilisant, comportant au moins une double liaison polymérisable et au moins un groupe fonctionnel électrophile. L'invention concerne également le mélange chimique pouvant être obtenu par ledit procédé, ainsi que l'utilisation du composé compatibilisant en vue de l'obtention de mélanges chimiques associant polyoléfine et poly(acide hydroxycarboxylique).
