氯化聚丙烯甲苯溶液的特性黏数及其黏均分子量

The intrinsic viscosity of chlorinated polypropylene-toluene and the viscosity average molecular weight of chlorinated polypropylene

分别用乌氏黏度计和旋转黏度计测定了氯化聚丙烯甲苯溶液的特性黏数和黏度,把特性黏数和黏度进行关联,发现ηsp/C与浓度C(ml/g)的关系用多项式ηsp/C=[η]+k1[η]2C+k2[η]2C2拟合,可以得到很好的结果。并且用特性黏数和Mark-Houwink方程求出了不同氯化聚丙烯(CPP)的黏均分子量。

The intrinsic viscosity and viscosity of chlorinated polypropylene-toluene being determined by Ubbelohde viscometer and rotary viscometer , it was found that the relation of η8p/C and eoneentration（C） was fitted with polynomial equationη8p/C=[η]＋ k1[η]^2C＋k2[η]^2C^2 and good results are gotten. The viscosity average molecular weights of several different chlorinated polypropylenes （CPPs） were calculated by the intrinsic viscosity and Mark-Houwink equation.
