AbstractThe functionalization of polyolefins has been an :ilea of scientific challenge and industrial importance for many years because the lack of polar groups in polyolefins significantly limits their applications In all of the ways, copolymerization with polar monomers is the most efficient one to functionalize polyolefins In this article, copolymerization of propylene with 10-undecen-1-ol and 10-undecenoic acid using triethylaluminum as the protection reagent has been performed in the TiCl(4)/MgCl(2)/diether/Al(C(2)H(5))(3) catalysis system In the presence of both comonomers, activity of copolymerization decreases with the increase of comonomer in the feed, but the decadence of polymerization activity is less With increasing polar monomer in the feed, the content of comonomer in copolymer increases. 10-Undecen-1-ol shows better performance, in terms of not only activity but also the comonomer content in copolymer With increasing the content of comonomer in copolymer, both melting point and crystallize temperature of copolymers decrease The polymerization temperature has less effect on polymerization activity and comonomer content in the copolymerization of propylene and 10-undecen-1-ol
