为了研究聚芳酯的化学结构与裂解产物的关系,本文合成了一系列化学结构不同的聚芳酯试样,在惰性气流中用装有炉式和居里点裂解器的裂解色谱仪进行热降解,分离后的裂解产物用质谱或标样鉴定,确立了裂解产物与聚芳酯化学结构的对应关系,并讨论了可能的热降解机理。 In order to study the relationship between the chemical structure of polyarylate and the pyrolysis products, a series of polyarylate samples with different chemical structures were synthesized and heated in a stream of inert gas using a pyrolysis chromatograph equipped with a furnace and Curie point cracker Degradation, separation of the cleavage products identified by mass spectrometry or standard sample, established the cleavage product and the chemical structure of the corresponding relationship between the polyarylate, and discussed possible thermal degradation mechanism.
