Abstract:
The present invention is directed to a method for preparing polyolefins containing a high percentage of exo-olefin chain ends. The method involves ionizing a polyolefin containing tert-chloride chain ends and reacting the ionized polyolefin with one or more nitrogen-containing five-membered aromatic ring or one or more hindered secondary or tertiary amines, or mixtures thereof.
