The effects of polypropylene-graft-maleic anhydride compatibilizer on the mechanical thermal and morphological properties of polyoxymethylene/polypropylene blends were investigated. Polyoxymethylene/polypropylene blends with and without polypropylene-graft-maleic anhydride compatibilizer were prepared by an internal mixer. The morphology of polyoxymethylene/polypropylene blends clearly demonstrated a two-phase separation of dispersed phase and the matrix phase and the addition of polypropylene-graft-maleic anhydride changed the morphological characteristics of blends. Polyoxymethylene/polypropylene blends showed the decrease of mechanical properties with increasing of polypropylene content. The addition of polypropylene-graft-maleic anhydride improved Young’s modulus and storage modulus of polyoxymethylene/polypropylene blends. The incorporation of polypropylene improved the degradation temperature of polyoxymethylene. 相似文献
