【Abstract】 he copolymerization of propene and octene- I using rac-Et(Ind)2ZrCl2 /MAO catalyst has been investigated. Results show that with increasing theconcentration of octene-l in the system, the catalytic activity increased first and then decreased, the incorporation rate of octene- I increased, and in consequence, M,Tm, crystallinity of copolymer decreased. The monomer composition and sequencedistribution of the copolymers were determined by IR and 13C-NMR.更多还原
