ABSTRACT:
A process for preparing alternating copolymer of butadiene and .alpha.-olefine which comprises contacting butadiene and the .alpha.-olefine in liquid phase with a catalyst system comprising the first component of AIR.sub.3 wherein R represents a hydrocarbon radical selected from the group consisting of alkyl, aryl and cycloalkyl radical in which at least one R is selected from the group consisting of alkyl having at least 3 carbon atoms per one molecule, aryl and cycloalkyl radical and the second component of TiX'.sub.4 wherein X' is selected from the group consisting of chlorine, bromine and iodine, or a catalyst system comprising the first component of AlR.sub.3 wherein R represents a hydrocarbon radical selected from the group consisting of alkyl, aryl and cycloalkyl radical, and the second component of TiX'.sub.4 wherein X' is the same as that defined above and the third component of a carbonyl group-containing compound. An alternating copolymer of butadiene and .alpha.-olefine, the microstructure of butadiene unit of the alternating copolymer contains cis-configuration. The alternating copolymers are rubber-like in character and can be used as polymeric plasticizers, in adhesives and can be vulcanized with sulfur or a sulfur compound to produce vulcanized elastomers.
