【Abstract】 The HDPE/EEA composition of different co-crystallization was crosslinked by 60 Co γ rays. The effect of co-crystallization on PTC properly of multivariate composition in polymer was investigated in the paper. The results showed that the co-crystallization of the multivariant composition could improve the PTC anomaly and thermal stability, but it didn’t take dominant effect on recoverability of switch temperature.更多还原
