一、引言在工业生产中和在实验室里,常要测定许多聚合物——溶剂体系的特性粘数。因此如何简化粘度法的实验操作和数据处理一直受到人们的重视。近年来此项工作的研究有了进一步的发展,已经提出几个有实际意义的一点法测定特性粘数经验公式。故设计一种连续和快速测定一个试样特性粘数的仪器是有理论依据和实用价值的。
I. INTRODUCTION In industrial processes and in laboratories, it is often desirable to determine the intrinsic viscosities of many polymer-solvent systems. Therefore, how to simplify the experimental operation and data processing of viscosity method has always been valued by people. In recent years, the work of this research has been further developed, has made a few practical significance of a point method to determine the intrinsic viscosity empirical formula. Therefore, the design of a continuous and rapid determination of a specimen intrinsic viscosity of the instrument is based on theory and practical value.
