过去报导过稀土催化体系丁二烯(BD)-异戊二烯(IP)共聚合。关于BD-IP共聚物微观结构及组成的分析方法,我们曾做过一些工作。本文所述是用红外(IR)和质子核磁共振(~1H-NMR)测定稀土催化体系的BD-IP共聚物组成的改进方法。
In the past, rare-earth catalyst systems such as butadiene (BD) -isoprene (IP) copolymerization were reported. About BD-IP copolymer microstructure and composition of the analytical methods, we have done some work. Described herein is an improved method for the determination of the BD-IP copolymer composition of rare earth catalytic systems by infrared (IR) and proton nuclear magnetic resonance (~ 1H-NMR).
