从高分子线团密度存在浓度依赖性角度出发,导出了从稀溶液至浓溶液范围内高分子链叠加度与浓度的定量关系式.以链叠加度为高分子溶液的结构参数,关联了文献中6种分子量的聚氯丁二烯在不同溶剂和温度条件下溶液相对黏度的变化.这表明,高分子溶液的宏观性质与溶液中高分子链叠加度这一微观结构参数密切相关.
From the point of concentration dependence of polymer linear density, the quantitative relationship between the superposition degree and the concentration of polymer chains from dilute solution to concentrated solution was deduced. The results showed that the macroscopical property of macromolecule solution was closely related to the microstructure parameter of superposition of polymer chains in solution.
