Abstract
According to a first form, the present invention relates to a compatibilizer composed of a polyolefin backbone and of polyamide grafts in which: The invention also relates to a process for the preparation of these compatibilizers in which, after the preparation of the backbone comprising the monomer having an activating functional group, the precursor lactam of the grafts and a catalyst are added and heating is carried out in order to obtain anionic polymerization of the lactam which spreads starting from the activating functional group. Subsequently, the compatibilizer and the polyamide which has formed apart from the grafts are optionally separated.
