Abstract

Abstract: The sorption mechanism of pure gases was extended to the sorption of binary mixtures in amorphous polymers by considering the effect of penetrant competition. The generalized model was supported by data of mixtures reported here for three systems (PMMA-CO2/ CH4,PMMA-C2H4/CH4and PS-C2H4/CH4) at the temperature of 308K.

摘要： 基于作者提出的纯气体吸收机理,并引入吸收竞争因子的概念,导出了混合气体在非晶态高分子膜内的吸收机理模型.针对PMMA—CO_2/CH_4、PMMA—C_2H_4/CH_4以及PS-C_2H_4/CH_4等3种系统,在308K的温度下进行了等温吸收实验.实验结果表明了上述模型能较好地描述混合气体的等温吸收数据.
