摘要
红外光谱法（ＦＴＩＲ）测定了（Ｃ６０Ｘ）载体钕系催化剂引发不同丁二烯异戊二烯摩尔比所得共聚物的组成变化规律，提出了球碳９７３ｃｍ－１吸收带可能与共聚物主链上双键与Ｃ６０分子骨架间存在ππ相互作用有关的解释。
The chain contents of copolymer of butadiene isoprene synthesized with Nd(naph) 3 Al(i噜 bu) 3 C 60 derivative catalyst system were determined by FT IR. The content of 3,4 chain of iosprene in copolymer rapidly decreased with the increasing of the content of butadiene in it. A new absorption band occured in polyisoprene and copolymer,973 cm -1 ,was attributed to the interaction between the π bond of main chain in polymer and π conjugation system in C 60 molecule.
