摘要
通过测定的聚酯特性黏度计算确定其聚合度是聚酯生产控制的关键环节 ,为此列举了目前国内厂家测定聚酯特性黏度的几种不同溶剂体系及其特性黏度的计算方法 ,并通过介绍质量比为 3 / 2的苯酚 四氯乙烷溶剂体系的特性黏度与分子质量的关系式 ,着重说明通过特性黏度计算聚酯聚合度的方法。
By the correct calculation of PET intrinsic viscosity to determine the polymerization degree is the key point in the control of proper production of high quality PET. The different solvent systems for measuring the relative viscosity of PET and the calculation method of intrinsic viscosity used in the domestic plants are enumerated. The calculation method of calculating PET polymerization degree with its intrinsic viscosity was emphatically explained by introduction the relation formula between intrinsic viscosity and molecular mass of the phenol and tetrachloroethane solvent system (mixing ratio 3/2 by mass).
