全芳香性螺环正碳酸酯的聚合及其产物的差热分析

Polymerization of Completely Aromatic Spiro Orthocarbonates and DTA Test of the Resulting Polymers

研究了邻苯二酚的螺环正碳酸酯、联苯二酚的螺环正碳酸酯以及联苯二酚与邻苯二酚交叉的螺环正碳酸酯在不同条件下的开环聚合。对部分产物进行了差热分析和特性粘度的测定。

The ring--opening polymerization of bis phenylene orthocarbo-nate, bis (2,2'--biphenylene) orthocarbonate and 2,2'--biphenylene phenylene-orthocarbonate was investigated under different conditions in this paper. TheDTA curve and the inherent viscosity were measured for some of the resulti-ng polymers.
