将不同共结晶度的高密度聚乙烯(HDPE)/乙烯—丙烯酸乙酯共聚物(EEA)复合体系经,60,Co γ射线辐射交联,考察该复合体系共结晶性对其正温度系数(PTC)特性影响。结果表明,共结晶提高该复合体系的开关温度畸变性和热稳定性,但对开关温度重现性影响不显著。
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.
