近来,随着高聚物溶液理論的发展,有关特性粘数、沉降系数及扩散系数的一些問題,如分子量的依賴性、溫度和溶剂的影响、高分子鏈的內旋轉阻碍度、支鏈的結构性质、分子量的多分散性、高分子鏈与溶剂間的相互作用力等的研究日趋完善。由于高聚物分子量的多分散性,分子量随測定方法不同而得出不同的統計平均值,因而各种不同的平均分子量之間有相当的差异。在訂定各种参数时,因有关的理論和分級实驗还不够完善,尚未能得到单分散的試样。正因为这样,对此有关的参数与分子量关系的研究富有重要意义。本文将介紹一些同高聚物溶液的摩擦性貭有关的理論和实驗結果。
Recently, with the development of polymer solution theory, some problems about intrinsic viscosity, sedimentation coefficient and diffusion coefficient, such as the dependence of molecular weight, the influence of temperature and solvent, the hindered internal rotation of polymer chain, The structural properties, the polydispersity of the molecular weight, the interaction force between the polymer chains and the solvent, etc., are perfected. Due to the polydispersity of the molecular weight of the polymer, different statistical averages are obtained depending on the method of determination of the molecular weight, and thus considerable differences exist among the different average molecular weights. In setting a variety of parameters, due to the relevant theory and grading experiments is not yet perfect, yet to get monodisperse sample. Because of this, the research on the relationship between parameters and molecular weight is of great significance. This article presents some theoretical and experimental results related to the tribological properties of polymer solutions.
