Abstract: The morphology structure of nylon-1010/PP-g-MAH blend systems,as well as nylon-1010/PP blends were studied. The Molau experiments and the IR analysis of the xylene extraction fractions of the blends showed that the reactions between -NH₂ or -NH-groups of nylon-1010 and maleic anhydride groups of PP-g-MAH took place during the melt blending, and the PP-g-NY1010 copolymer formed by the reactions acted as a compatibilizer. Also it could be found from the SEM photographs that the affinity between the nylon-1010 and PP-g-MAH was improved to some extent as compared with that of nylon-1010lPP blends.

Key words: nylon-1010, maleic anhydride, grafting, polypropylene, blend
