Abstract: The synthesis of propylene/decene-1 copolymer by TiCl4/MgCl2 catalyst and propylene/octene-1 copolymer by δ-TiCl3 catalyst has been investigated.The effects of [Al]/[Ti] ratio,temperature,and concentration of monomers on the copolymerization have been studied.The higher catalysis efficiency,the larger particle size and more porous surface of polymer were observed in copolymerization in comparison with that in homopolymerization of propylene.The results are discussed in terms of the unsteady diffusion kinetics of the heterogeneous Ziegler-Natta polymerization.

Key words: propylene, octene, decene, copolymerization, Ziegler-Natta catalyst
