【摘要】 本文用裂解色谱(PGC)、裂解-色谱质谱(PY-GC/MS)和裂解质谱(PY/MS)等方法对异戊二烯-甲基丙烯酸甲酯共聚物进行了裂解研究,分离鉴定了主要裂解产物,检测出了特征裂解产物——杂二聚体和杂三聚体,以及异戊二烯的三聚体。考察了某些主要裂解产物同无规共聚物的组分含量和裂解温度之间的变化关系。建立了用裂解色谱鉴卡拉奇不同共聚物和均聚混合物以及分析无规共聚物组分含量的方法。定量方法的精确度为相对标准偏差小于2％。对用均聚混合物作标样的定量可能性进行了探讨。更多还原

【Abstract】 Pyrolytic investigations on copol mer of isonrene and methyl methacrylate have been carried out by means of pyrolysis-gas cbro-matography, Pyrolysis-gas Chromato raphy-mass spectrometry and pyrolysis-mass spectrometry. In addition to the main ryrolytic products, the characteristic products, such as hybrid dimer and hybrid trmers, have also been defected. The analytical method for determining the composition of- random ( has been established and the relative standard deviation was less than 2%. The quant:tative method by using physica blend of homopol mers as the standard sample was discussed.更多还原
