摘要：

Atactic and isotactic polypropylenes having terminal vinylidene groups were prepared with bis(cyclopentadienyl)zirconium dichloride-and ethylenebis(4,5,6,7-tetrahydro-1-indenyl)zirconium dichloride-methylaluminoxane catalyst systems. The produced polymers having a vinylidene end group were treated with an excess of borane in benzene, followed by treatment with an excess of 1-hexene. The resulting trialkylboranes were disproportionated with boron trichloride in xylene at 110-degrees-C to obtain alkyldichloroboranes. The products were then brought into contact with 1-butylazide to obtain the polypropylenes having a 1-butylamino group at the chain end in over 80% yield.
