Abstract:
Homopolymerization of 1,7-octadiene and copolymerizations of 1-hexene and 1,7-octadiene were carried out by the metallocene catalyst system rac-Et(Ind)2ZrCl2/MMAO. The catalyst activity has slightly increased with the addition of low amounts of the diene in relation to the copolymerization of 1-hexene and 1,7-octadiene. On the basis of the FTIR spectra, the polymer was assigned a hydrocarbon chain structure. Microstructures of the homopolymer and copolymers were determined by 1H NMR and also diene contents in the copolymer were obtained through 1H NMR. The results indicated that with the addition of diene, incorporation of nonconjugated diene in the copolymer increased
