| Abstract: | In contrast to maleic anhydride PP graft polymer (MPP), the mechanisms of compatibilization of itaconic acid PP graft polymer (IPP) on PA6 rich PA6/PP blends were investigated by means of ESCA, SAXS, WAXD, SEM and mechanical property tests. The formation of new PA gPP copolymers in the blends was confirmed. The relationships between the structure of gPP and PA co gPP and the formation quantity and compatilizing efficiency of PA co gPP were discussed and the compatibilization models of PA co MPP and PA co IPP were proposed. |
