Analysis of polyacrylonitrile and copolymers of acrylonitrile by pyrolysis-gas chromatography/mass spectrometry

Polyacrylonitrile and several copolymers(acrylonitrile styrene,acrylonitrile butadiene and acrylonitrile butadiene styrene) of acrylonitrile were analyzed by PY GC/MS. Monomer and characteristic compounds of relevant structure of polyacrylonitrile and several copolymers of acrylonitrile were obtained. At the same time, the pyrolysis mechanism of the several polymers was discussed theoretically.
