应用裂解色谱—质谱(PGC—MS)法研究化学法和等离子体法聚合得到的聚乙烯的裂解行为。比较了两种聚合物的结构差异。探讨了等离子体聚合条件对聚合物结构的影响及其聚合反应机理。 The pyrolysis behavior of polyethylene obtained by chemical and plasma polymerization was studied by using pyrolysis chromatography-mass spectrometry (PGC-MS). The structural differences between the two polymers were compared. The effects of plasma polymerization conditions on the polymer structure and the polymerization mechanism were discussed.
