Abstract

The present invention is directed to a method for preparation of polyolefins containing exo-olefin chain ends. The method involves quenching a cationic quasi-living polyolefin polymer system with a nitrogen-containing five-membered aromatic ring having at least two hydrocarbyl substituent compounds attached to the ring.
