Abstract
Esterexchange reaction was a useful method to improve the compatibility of polymer blends In this article esteramide exchange reaction between Nylon 1010 and Ethylenevinyl acetate rubber EVM was studied in the presence of different Ti and Zn derivatives as catalysts The chemical reactions were studied by 1H NMR Catalytic activities of TiOBu4 TiOOOCCH32 ZnO and ZnOOCCH32 were compared and TiOBu4 showed the highest catalytic reactivity Melt flow index MFI of Nylon 1010/EVM blends indicated that crosslinking and degradation took place in the reactive blends Gel permeation chromatography GPC provided the evidence for the degradation behavior during melt blending SEM images showed that the compatibility of the blends was improved at the presence of catalyst SAXS results showed that the long period of Nylon 1010/EVM decreased after adding TiOBu4 implying the formation of imperfect crystallites in Nylon 1010/EVM/TiOBu4 blend
