摘要

本文论述了不溶于水－乙醇体系的凝胶化的聚乙烯醇缩甲醛（ＰＶＦ）缩醛度测定的方法．通过反复实验找到一种合适的溶剂体系，使测定方法简便、准确，并通过对比实验验证了该方法的可靠性和准确性．

Abstract

In this paper

a new solvent system used to determine the degree of acetals of polyvinvl formal is discussed. Base on a series of experiments

an adaptive solvant is found and its reliability and preciseness are proved.
