Abstract:
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.

Claim (Index 26):
A method form making the initiator molecule claimed in  claim 1  comprising:\n A. dissolving 1,2,4,5-tetramethyl benzene or 1,2,3,5-tetramethyl benzene in a suitable solvent; \n B. combining an acetyl halide, aluminum chloride, and a dry solvent in a suitable container and heating it to reflux for from about 6 to about 12 hours; \n C. adding the solution of step A to the solution of step B and stirring at reflux for an additional 10 to 14 hours; \n D. separating the resulting polymer containing solution into organic and aqueous phases, washing the resulting organic phase with aqueous sodium carbonate, removing the solvent, and drying the resulting product to produce the corresponding diethanone; \n E. dissolving said corresponding diethanone in a suitable solvent and irradiating it with ultraviolet light to form the corresponding bis-benzocyclobutenol initiator molecule.
