| 摘要 |
According to a first form, the present invention relates to a compatibilizer composed of a polyolefin backbone and of polyamide grafts in which: the grafts are attached to the backbone via the residues of an unsaturated monomer (A) having a functional group which acts as activator in the polymerization of lactains and which is not an isocyanate functional group, the residues of the unsaturated monomer (A) are fixed to the backbone by grafting from its double bond. 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. |
