三元共聚丙烯腈纤维的一点法粘度式

ONE-POINT METHOD FOR DETERMINATION OF INTRINSIC VISCOSITY OF TERPOLYMER ACRYLONITRILE FIBER

本工作以山东淄博合成纤维厂生产的三元共聚丙烯腈纤维为样品将其分成十一个级分,分别用四个不同方法制定的一点法粘度式计算该纤维和十一个级分的[η](特性粘数),并与经典方法Huggins方程求出的[η]比较,得到适合于工厂推广应用的一点法粘度式。

The intrinsic viscosities of the sample terpolymer acrylonitrile fiber which is divided into eleven classes were measured and calculated by one-point method. Incomparison with the intrinsic viscosities obtained by the Huggins and Kurata equa-tions, an appropriate one suitable for the plant application has been proposed.
