摘要

Catalysts and processes are described to make low molecular weight,essentially terminally-unsaturated, viscouspoly(1-olefin) or copoly(1-olefin) having a high terminal vinylidine contentfrom a feed stock containing one or more 1-olefin andother volatile hydrocarbon liquids using a Ziegler catalyst made from a GroupIVb metallocene and an aluminoxane cocatalyst,particularly bis(cyclopentadienyl) and bis(indenyl) titanium(IV),zirconium(IV) or hafnium(IV) compounds and methylaluminoxane.A particularly useful feed stock is a refinery stream containing 1-olefins andisobutylene which is used to make polyisobutylene.The reactive, essentially terminally-unsaturated, viscous poly(1-olefin) orcopoly(1-olefin) can be functionalized to make anumber of products useful as sealants, petroleum additives, adhesives, and thelike by reacting the terminal vinylidine linkagewith an aromatic, an epoxidation agent, a silylation agent, maleic anhydride,carbon monoxide and hydrogen, hydrogen, a halogen,a hydrohalogen, and the like.
