聚丙烯腈及丙烯腈共聚物的PY-GC/MS分析
Analysis of polyacrylonitrile and copolymers of acrylonitrile by pyrolysis-gas chromatography/mass spectrometry
【摘要】 采用热裂解 气相色谱 /质谱法 (PY GC/MS)对聚丙烯腈及丙烯腈的几种共聚物 (AS树脂、NBR橡胶和ABS树脂 )进行了分析 ,获得了有关聚丙烯腈及这几种共聚物结构的单体和特征化合物。并从理论方面讨论了它们的热裂解机理
【Abstract】 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.
