ABSTRACT: The mechanical, morphological and thermo-oxidative aging properties of the glass fiber reinforced polypropylene (RGF-PP) were studied based on four different maleic anhydride grafted polypropylene (PP-g-MAH) compatibilizers with different content of residual maleic anhydride (MAH). It was shown that PP-g-MAH compatibilizer could significantly improve the mechanical properties of RGF-PP, while from thermal and morphological analysis results, the content of residual MAH had negative influence on long term thermo- oxidative aging properties of RGF-PP with adding PP-g-MAH compatibilizer; the lower the residual content of MAH is, the better the thermo stability of the PP-g-MAH is, and also the better the thermo-oxidative aging properties was obtained.
