摘要

Copolymerization of ethylene/1-octene was carried out in toluene withvarious concentrations of comonomer in the feed using Et(Ind)2ZrCl2/MAO (methyl alu-minoxane) as catalyst. It was found that with the increase of 1-octene concentration in thefeed the content of 1-octene in the copolymer increases

while the density

melting point

crystallinity and intrinsic viscosity of copolymer decrease. A copolymer with very lowdensity

containing 11.5 mol% of 1-octene (VLLDPE) can be produced with this catalyst system.The effect of temperature and zirconium aluminum mole ratio of the catalyst on the copolymerization was also investigated.The results of 13C NMR determination of the copolymer showed that the 1-octene units in the copolymer are principally isolated.
