| 英文摘要 | The change of compatibility of poly(ethylene-co-vinyl alcohol) (evoh)/ldpe blends induced by gamma-ray radiation was studied. gel extraction experiment results show that the gel fraction of blends increases linearly with the content of ldpe and reaches a maximum at 100 kgy, because neat evoh is difficult to cross-link by irradiation. a comparison of theoretical and experimental gel contents indicates that some evoh molecular chains enter the ldpe gel network. the peak at 3363 cm(-1) on the fourier transform infrared spectrum of pure blend gel is assigned to typical stretching of an -oh bond, which indicates that a "graft" reaction occurs in the interface between evoh and ldpe phases during the irradiation process. mechanical property measurement results support such a structural change. the tensile strength of cross-linked blends increases with absorbed dose first, reaches a maximum value at 150 kgy, and then decreases with dose. a similar trend can also be observed in bending tests.
