有关丁二烯-异戊二烯共聚物的动态力学性能的研究报导不多。Labach及谢德民报导了共聚物序列分布的研究.文献(3)报导了稀土丁/异戊共聚物的低温特性。 本文工作采用TPA,~(13)C-NMR,X-衍射等方法研究了稀土催化丁二烯-异戊二烯共聚 There are not many reports on the dynamic mechanical properties of butadiene-isoprene copolymers. Labach and Shumin reported the study of copolymer sequence distribution (3) reported the low temperature properties of the rare earth butyl / isoprene copolymer. In this work, the use of TPA, ~ (13) C-NMR, X-ray diffraction and other methods to study the rare earth catalyst butadiene-isoprene copolymerization
