ABSTRACT:
A process and catalyst system for the preparation of diene oligomers and copolymeric oligomers is disclosed. The oligomers and copolymers are prepared in an alkane solvent from one or more 1,3-diene monomers using a secondary amine transfer agent and an anionic initiator. A catalyst system including a secondary amine transfer agent and an anionic initiator is also provided.
