摘要
本文用光散身的粘度法研究了一种含酞侧基的聚醚醚酮(PEK-C)在氯仿(CKCl_3)和二甲基酰胺(DMF)中的稀溶液性质,建立了PEK-C在两种溶剂中的Mark-Houwink方程:并得到了高分子一溶剂相互作用参数χ_1和PEK-C的特征常数K_θ值: K_θ=6.25×10^(-2)ml/g,X_1=0.48,CHCl_3 K_θ=4.42×10^(-2)ml/g,X_1=0.49,DMF以及流体力学扩张因子α_η~3与分子量间的函数关系。
The solution properties of PEK-C in CHCl_3 and DMF were investigated by light scattering and viscometric methods. Two Mark-Houwink equations and interaction parameters were obtained respectively:K_θ values of PEK-C have also been obtained from M and [η] according to Stockmayer-Fixman with K_θ=6.25×10^(-2)ml/g (CHCl_3),K_θ=4.42×10^(-2)ml/g (DMF). Simultaneously, the dependances of expansion factors α_η~3 on M^(1/2) were discussed.
