摘要
综合使用核磁、VPO和近红外光谱分析技术对聚异丁烯活性端基含量以及相对分子质量的测定进行了详细研究。分别建立核磁测定聚异丁烯活性端基含量以及其他烯键含量和近红外光谱快速测定聚异丁烯活性端基含量、其他烯键含量和相对分子质量的分析方法。成对t检验结果表明 ,近红外光谱分析方法测定结果与核磁和VPO方法测定结果之间无显著性差异。
This paper researches measuring method of high active end group content and molecular weight of polyisobutene using nuclear magnetic resonance, vapour pressure osmosis and near infrared spectra. The methods of determining high active end group content and molecular weight of polyisobutene have been established by nuclear magnetic resonance and near infrared spectra respectively. Twin t-test results indicated that near infrared spectra method is coincidence with nuclear magnetic resonance and vapour pressure osmosis method.
