摘要
用ＤＳＣ观测了溶液浇铸ＰＭＭＡ薄膜的热焓松弛行为，对物理老化、溶液浓度以及溶剂极性对其热焓松弛行为的影响进行了详细的讨论，其特征用凝聚缠结的观点予以解释。
The enthalpy relaxation behavior of solution cast poly(methyl methacrylate)(PMMA) films has been studied using differential scanning calorimeter. The influence of physical aging, solution concentrations and polarities of solvents on the enthalpy relaxation was discussed and interpreted in terms of the concept of cohensional entanglements.
