聚芳砜热降解残余物性能的研究

A STUDY OF THE PROPERTIES OF RESIDUE FROM THERMAL DECOMPOSITION OF POLYSULFONE

由双酚A和4,4′-二氯二苯基砜合成制得的聚芳砜具有良好的力学性能,聚芳砜在高温下的热裂解行为以及降解机理等也有过报道,但是对裂解残余物的性质及其与降解机理的关系却未得到注意,Hale等曾指出热降解后的碳化残余物是完全不溶的。

Polysulfone was decomposed thermally in an inert atmosphere, leaving 30-40% by weight of the initial sample as residue. It was found that the residue has good conductivity and good crystalline structure.
