Binary blends of polypropylene (PP)/recycled poly(ethylene terephthalate) (r-PET); r-PET/maleic anhydride grafted PP (PP-g-MA); r-PET/glycidyl methacrylate grafted PP (PP-g-GMA); and ternary blends of PP/r-PET (80/20 w/w) compatibilized with various amounts (2-10 wt%) of PP-g-MA or PP-g-GMA were prepared on a twin-screw extruder. The non-isothermal crystallization and melting behavior; and the crystallization morphology were investigated by DSC and POM. The chemical reactions of r-PET with PP-g-MA and PP-g-GMA were characterized by FT-IR. DSC results show that the crystallization peak temperatures (Tcp) of r-PET and PP increased when blending them together; due to the heterogeneous nucleation effect on each other. The Tcp of r-PET increased with increasing the content of PP-g-MA while slightly influenced by the content of PP-g-GMA in the binary blends of r-PET with grafted PP; implying different reactivity of r-PET with PP-g-MA and PP-g-GMA. The Tcp of PP in the ternary blends retained or slightly decreased; dependent on the compatibilizers and their contents. The melting peak temperature (Tmp) of r-PET in PP/r-PET blends compatibilized by PP-g-MA was lower than that of compatibilized by PP-g-GMA; indicating that PP-g-MA had stronger reactivity towards r-PET compared to PP-g-GMA. The crystallization and melting behavior of blends was influenced by the pre-melting temperature; especially the melting behavior of r-PET in the blends. The crystallization behavior of PP in the blends was also evaluated by Mo's method. POM confirmed the heterogeneous nucleation effect of r-PET on PP. © 2007 Elsevier Ltd. All rights reserved;
