摘要
本文对PEW(PEW)在溶剂中的溶解度和溶解时间进行了测定,研究了PEW分子量、溶解温度对溶解度和溶解时间的影响。采用溶解方法对灰色PEW进行了脱色试验,通过白度、原子吸收分光光度分析证明,PEW中的有色杂质被有效去除,并初步认定有色杂质可能来自于聚合体系中的引发剂。
In this article, the solubility and time of solution in solvents of PEW were determined. Effects of molecular weight and solution temperature of PEW on solubility and time of solution were studied. The experiment of decolourization for grey PEW was carried by using the method of solution. The result proved by the analysis of whiteness and atomic absorption photometry, the colored impurities in PEW could be removed efficiently, and affirmed initially the colored impurities might come from the initiator in the system of polymerization.
