摘要: 聚合物共混物经辐射交联后,具有多种优良性能,这些性能都与交联度有关。溶胶分数与辐照剂量间的关系常常被用来表征聚合物的辐射交联程度和交联行为。本文试图将共混物的组成、组份的分子链结构与其溶胶分数与辐照剂量间的关系式联系起来,从而预期共混体系的辐射交联行为。

Abstract: The radiation crosslinking of LDPE/1,2-PBd blend has been studied. The experimentalresults show that the relationshipR(S+√S)=1/q0U1+p0′Rβ/q0 is also suitable to LDPE/1,2-PBd blend system. The method to calculate the βb value ofpolymer blend system has been established.
