Abstract: This paper describes an apparatus for measuring both pure and mixed gas sorption in amorphous polymers. Sorption data were reported for pure gases (CO2, CH4, C2H4 and C2H6) in three amorphous polymers[poly(methal methacry-lateXPMMA), pplyimde(PI) and poly(vinyl acetate) (PVA)]. These results and some data reported in literature show that the sorption model developed in Part I of this series can be applied to amorphous polymers both above and below the glass-transition temperature and that the model parameters can be correlated with the molecular properties and characteristics of the polymers and penetrant.

摘要： 对CO_2、CH_4、C_2H_4和C_2H_6等4种纯气体进行了吸收等温线的测试,通过数据表明在(Ⅰ)报中提出的吸收机理模型是普遍适用的,模型参数也能较好地与高分子和渗透分子的物性数据关联.
