Polymerisation of 1,5-hexadienes

[摘要] ENGLISH ABSTRACT:In this study, the feasibility of the non-conjugated 1,5-hexadiene as monomer inmetallocene catalised cyclopolymerizations was considered. Homopolymers andcopolymers with ethylene, propylene, 1-pentene, 1-hexene and 2-methyl-1,5-hexadiene as comonomers were synthesised in the presence of Cp2ZrCh andrac-Et(lnd)2Zrh. The microstructure (stereoregularity and cyclisation) andnumber-average molecular weight were determined from NMR analysis.Crystalline oligomers with functional (eg -OH) and vinylidene end groups wereobtained.
