摘要
依据最近提出的高分子稀溶液粘度的浓度 依赖性的团簇理论 ,对高分子‘理想混合物’的定义进行了更新的理论分析 .在此基础上提出了一个新的判定高分子相容性的粘度判据 .从现有的大量实验数据看 。
According to a new cluster theory for the concentration-dependence of polymer solution viscosity proposed recently, the concept 'ideal polymer mixture' was re-investigated and defined as one in which there does not exist any net attractive interaction between unlike polymers which could result in inter-chain association between unlike polymers. Based on the new definition,, a new viscometric criterion for,polymer-polymer miscibility was suggested. Namely, if the overall apparent association constant obtained experimentally (< K-m >(exp)) of a mixture solution deviates positively from the weight-averaged value of the two components' apparent association constants, the mixture could be judged as miscible. It was found that the new criterion agrees well with experimental data.
