【摘要】 高分子-溶剂体系的折光指数增量(dn/dc)有明显的温度依赖性和分子量依赖性,在研究不同温度的光散射行为,或以低分子量高聚物为研究试样时,若不考虑dn/dc的温度和分子量依赖性,将给光散射实验的计算结果带来不容忽视的误差,而必须予以充分重视。更多还原

【Abstract】 In this paper we mentioned that the temperature and moleculai weight dependence of the refractive index increment dn/dc must be take into account for molecular weight and second virial coefficient AZ measurements by light scattering method.更多还原
