| abstract |
The present invention provides a new copolymer of propylene and a conjugated diene having a carbon-carbon double bond in a side chain, wherein a molar ratio of a total of 1,2-adducts and 3,4-adducts to 1,4-adducts, derived from the conjugated diene, is 100:0. The copolymer is prepared in a process, characterized in that propylene and the conjugated diene are copolymerized in the presence of hydrogen, an organometallic compound comprising a transition metal selected from the group 4 of the periodic table, and at least one Lewis acid. |
