悬浮PVC聚合体系中分散剂过量的判定

Judgement on the excess of dispersants in PVC suspension polymerization system

指出了PVC悬浮聚合时分散剂浓度过高时易析出凝胶,提出了一种用四氢呋喃来溶解离心母液滤出物来判定分散剂过量的方法。

It was indicated that high dispersants content in PVC suspension polymerization system could lead to the precipitation of gelatin. A method for the judgement on the excess of dispersants was proposed, i.e. dissolving filter residues of centrifugal mother liquid with tetrahydrofuran.
