Norbornene polymers with intrinsic porosity were investigated as candidates for polymeric stationary phases in capillary GC. Kinetic and thermodynamic characteristics of the stationary phases were evaluated and turned out that only polymer with vicinal distribution of trimethylsilyl groups (polymer II) provided properties making it potential candidate for application in capillary GC. Columns with stationary phase based on polymer II demonstrated unique selectivity, moderate thermostability and efficiency better than previously studied columns with stationary phase based on poly[(1-trimethylsilyl)-1-propine].
研究了具有本征多孔性的降冰片烯聚合物，将其作为毛细管 GC 中聚合物固定相的候选物。评估了固定相的动力学和热力学特性，结果表明，只有具有三甲基硅基邻位分布的聚合物（聚合物 II）提供了使其成为毛细管 GC 应用潜在候选物的特性。基于聚合物 II 的固定相的色谱柱表现出独特的选择性、中等的热稳定性和效率，优于以前研究过的基于聚[(1-三甲基硅基)-1-丙烯]的固定相的色谱柱。
