巨乙烯的輻射交联效应的研究,到目前为止已积累了大量实驗数据,在分析和解释交联高巨物的溶胶分数数据肘,作者們都引用Charlesby的溶胶凝胶分配公式,結果实驗数据同理論不能很好地符合,但对其原因都研究的很少。本工作为了探討这不符合的原因,对高压巨乙烯的輻射交联效应进行了研究。通过用本文所建議的方法从溶胶分数和体积溶胀比数据的分析得到了起始分子量分布,并討論了交联度和裂解度与起始分子量分布和剂量的关系,最后指出Charlesby的溶胶凝胶分配公式与实驗不符合的原因所在。
So far, a large number of experimental data have been accumulated. In analyzing and interpreting the sol-gel data of the cross-linked tall objects, the authors all refer to the sol-gel distribution formula of Charlesby. The experimental data The same theory does not fit very well, but there are few studies on its causes. This work in order to explore the reasons for this does not meet the high pressure of ethylene radiation crosslinking effect were studied. The initial molecular weight distribution was obtained from the analysis of the sol fraction and the volume swell ratio data by the method proposed in this article and the relationship between the degree of crosslinking and the degree of cracking and the initial molecular weight distribution and dose was discussed. Finally, it was pointed out that Charlesby’s sol- The reason why the distribution formula does not conform to the experiment.
