| 摘 要： | 本文对橡胶类型—聚异丁烯的浓度效应进行了研究,用多分散试样的模型理论所推导出的关系式,处理了多分散聚异丁烯(=2.8×10~4～22.0×10~4;=2.20～3.92,C=0.05～1.20g/100ml)试样实验数据,得到了理论与实验很好符合的结果。这证明了所提出的多分散试样的模型理论适用于柔性链线型高聚物。

| Abstract: | In this paper the concentration effects of injected polymers on the effective hydrodynamic volumes, the clution volumes and the polydispersed index of nydrodynamic volumes for polydispersed polyisobutylene in THF solvent were studied. The proposed model theory of concentration effects was verified by these experimental data of PIB. The results show that the proposed theory can predict the concentration effects in GPC for flexible linear polymers with polydispersity. |
