In various embodiments, the present invention is directed to new low cost initiator compositions for use with the production of well-defined telechelic PIBs (by LC+P of isobutylene). In various other embodiments, the present invention is directed to methods for using these novel compositions as initiators for isobutylene (IB) and other cationically polymerizable monomers, such as styrene and its derivatives. In still other embodiments, the present invention is directed to structurally new, allyl (and chlorine) telechelic PIBs formed from these new initiator compositions and their derivatives (in particular, hydroxyl telechelic PIB and amine telechelic PIB). In yet other embodiments, the present invention is directed to structurally new polyurethanes, polyureas, and polyurethane ureas made using telechelic PIBs formed from these new initiator compositions.
