| Abstract
| - The copolymerizations of propylene with allyl monomers carrying alcohol or amine wereconducted by the rac-dimethylsilylbis(1-indenyl)zirconium dichloride/methylaluminoxane catalyst system.The allyl monomers were pretreated by alkylaluminum before the polymerization. Although the efficiencyof the introduction of allyl alcohol-based comonomer was extraordinary low (0.04−0.08 mol % in polymer),the trimethylaluminum-treated allylamine was found to be introduced more effectively (0.65 mol % inpolymer). The 13C NMR study indicated that the position of allylamine unit in the copolymer was influencedby the kind of alkylaluminum used at the polymerization. In the presence of trimethylaluminum, theterminally aminated polypropylene was obtained ([amino end polymer]/[whole polymer] = 0.83). In thepresence of triisobutylaluminum, however, the allylamine unit is located both on the main chain and atthe chain end. The end-aminated polymer was probably obtained due to the formation of dormant speciesafter the insertion of the comonomer followed by the chain transfer to alkylaluminum.
