摘要：

The mechanism of the reactive pyrolysis of an aromatic polyester sample in the presence of tetramethylammonium hydroxide (TMAH) solution is studied by pyrolysis-gas chromatography/mass spectrometry. The contribution of solvent (methanol) is evaluated by use of a deuterated methanol solution of TMAH. The results obtained suggest that methyl derivatives are formed not only through hydrolysis by TMAH but also through methanolysis to some extent. Further, the study of the influence of coexisting alkali salt impurities in the reagent on the reactive pyrolysis reveals that the presence of such alkali salts hinders the quantitative derivatization of the aromatic polyesters into the methyl esters of constituents.
