摘要：

The thermal degradation products formed from epoxy resins of the diglycidyl ether of bisphenol A and the tetraglycidyl ether of tetrakis(hydroxyphenyl)ethane have been investigated by temperature-resolved in-source pyrolysis-field ionization mass spectrometry (Py-FIMS). Intense signals from thermal degradation products in the mass range m/z 50-900 were detected. Molecular ions containing up to three intact bisphenol A subunits were found as main degradation products, with rearrangement reactions being involved in the formation of abundant high-mass products. Most products contain at least one phenolic end group.
