中文摘要	reactive compatibilization of ethylene-propylene copolymer functionalized with allyl (3-isocyanato-4-tolyl) carbamate (tai) isocyanate (epm-g-tai) and polyamide 6 (pa6) was investigated in this paper, ftir analysis revealed the evidence of a chemical reaction between the end groups of pa6 and epm-g-tai. thermal, rheological, morphological, and mechanical properties of the resultant system were examined, dsc analysis indicated that the crystallization of pa6 in pa6/epm-g-tai blends was inhibited, due to the chemical reaction that occurs at the interface of pa6 and epm-g-tai. rheological measurement showed that complex viscosity and storage modulus of pa6/epm-g-tai were both dramatically enhanced compared to those of pa6/epm at the same blending composition. after examining the morphology of both blending systems, smaller particile sizes, more homogeneous distribution of domains and improved interfacial adhesion between matrix and domains were observed in the compatibilized system. mechanical properties such as tensile strength. young's modulus, flexural strength and modulus, as well as notched and un-notched impact strength of pa6/epm-g-tai blends were also found to improve gradually with increasing the content of grafted tai.
