STUDIES ON THE INTERFACIAL ADHESION BETWEEN FUNCTIONALIZED POLYPROPYLENE AND POLYAMIDE 1010*

Received Date: 4 January 1998

The interface behavior of polyamide 1010 (PA1010) and polypropylene (PP) was studied. In orderto improve their interfacial adhesion, functional PP was prepared by means of grafting glycidyl methacrylate(GMA) on PP main chains and used instead of plain PP. Several technological characterizations wereperformed here on their interfaces. ESCA was used to confirm that some kind of reaction occurred betweenend groups of PA1010 and epoxy species of PP-g-GMA. The peel test was adopted to measure interfacial adhesion.It was found that the fracture energy of interfaces between PA1010 and PP-g-GMA was dramatically increased with the content of GMA.Their interfaces were obserevd as being blurred by using SEM and TEM and a crack that could be seen in the case of the interfaces of the PA1010 and the plain PP disappeared.
