Fund Project:

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 homopolymerizationof propylene.The results are discussed in terms of the unsteady diffusion kinetics of the heterogeneous Ziegler-Natta polymerization.
