Title:The Analysis of Polymer by Pyrolysis Gas Chromatography-Mass Spectrometry
Abstract
In recent years, much attention has been paid to the research of polymer using pyrolysis gas chromatography-mass spectrometry method. Monomer, dimmer, trimer and the structure information of the various additives are obtained by pyrolysis gas chromatography-mass spectrometry technique (GC/MS) from homopolymer, copolymer and terpolymer. According to the information, the linked manners of copolymer chain and the framework structures are known and concluded, respectively. Thus, the structure information of polymer can be characterized by pyrolysis GC/MS, which provides an effective means for polymer research.
In my paper, the fragmentation of the polymer of carbon dioxide and epoxy propane is studied by pyrolysis GC/MS at high temperature. By comparing the fragments of the polymer of carbon dioxide and epoxy propane at different temperature, the optimal temperature for fragmentation is confirmed. The fragments are separated by gas chromatography and analyzed by mass spectrometry. The research of the fragmentation of polymer at different temperature as well as the comparison of fragments at different temperature, which provides the referenced data for pyrolysis mechanism at high temperature for the future.
