摘要: 作为一种结构参数,聚合物的分子链内旋转位阻因子可表征聚合物分子链的柔顺性,并与聚合物的许多物理性质相关联。过去实验事实表明,聚合物的辐射交联行为与其分子链柔顺性密切相关。本工作从这一结论出发,研究聚合物的分子链内旋转让阻因子(σ)与其交联参数β之间的关系,为估算聚合物σ值提供一种新方法。

Abstract: A relationship between the molecular internal rotating steric factor (σ) and crosslink-ing parameter(β) is established by taking the effect of the flexibility of polymer chain on β value into account. The σ value obtained by this method is close to those reported in the literature by other methods.
