质谱法研究聚碳酸酯低聚体结构

Study on the oligomer structurue in polycarbonate by masss pectrometry

用气相色谱 质谱和场解吸 质谱方法研究聚碳酸酯的乙醇萃取物。发现由溶剂法合成的聚碳酸酯中含有以氯酸甲酯和对 叔丁基苯酚为端基的低聚体。

The oligomer structure in polycarbonate(PC)was studied by combination of GC-MS and FD-MS in the ethanol extract of PC.More than nine oligomers with chlorofomate and tere-But-PhOH end-groups in the PC synthesized by solvent method were identified.
