Polyolefins with reactive functional groups at both chain ends represent a potentially versatile route for the synthesis of multi-block copolymers possessing a polyolefin core. This presentation will focus on our recent efforts in developing catalytic coordinative chain transfer polymerization (CCTP) of olefins using bidirectional chain transfer agents (CTAs). The consequences of altering the metal and diyl structure in the CTA scaffold on the performance of the CCTP by modulating solubility, the stability of the organometallic end groups, and the relative rates of propagation, chain transfer, and termination will be discussed. Silicon-containing CTAs were found to have superior solubility versus simple hydrocarbon analogues, which allows the CCTP reactions to be conducted under milder conditions.<br/>
