本文采用固上顶空－气相色谱法分析了三种高聚物中的微量残留单体和低聚物。从分析结果可看出，三种高聚物中都有一定数量的残留单体，其中，不合格聚乙烯中存在大量的低聚物。说明单体在聚合过程中反应过早终止，可能是由于聚合反应条件不当或催化剂活性下降引起。未知组分的定性采用气相色谱－质谱联用技术，定量方法为外标法。
In this paper, solid headspace-gas chromatography was used to analyze trace amounts of residual monomers and oligomers in three polymers. It can be seen from the analysis results that there are a certain amount of residual monomers in all three polymers, wherein a large amount of oligomers are present in the unqualified polyethylene. Indicating monomer premature termination of the polymerization process may be due to improper polymerization conditions or catalyst activity caused by decline. Qualitative determination of unknown components using gas chromatography - mass spectrometry, quantitative methods for the external standard method.
