viscous state

Effect of temperature,weight concentration of CaCl2,inherent viscosity of copolymer and mole fraction of ODA on the parameters of copolymer solution,Non-Newton exponent,viscous activation energy and structural .

研究了溶液中共聚物质量分数、温度、CaCl2质量分数、共聚物的比浓对数黏度和ODA的摩尔分数对PPTA三元共聚物溶液的非牛顿指数、黏流活化能、结构黏度指数等重要参数的影响,为纺丝工艺的制定提供重要依据。
