摘要：
The present invention is directed to a polymer comprising repeat units derived from 1,3-butadiene and a substituted butadiene of formula I or II wherein R is hydrogen, an alkyl group, aryl group, or a fused cyclic group; and wherein at least 95 percent by weight of the repeat units have a cis-1, 4 microstructure. The invention is further directed to a rubber composition and pneumatic tire comprising the polymer, and a method for making the polymer using a neodymium catalyst system.
