Abstract
The influence of di-n-butyl ether (DBE) on the characteristics of Ziegler-N atta catalysts evaluated in propylene polymerization was investigated. The catalysts were synthesized by the reduction of TiCl4 in toluene solution wi th AlEt3 . DBE complex at various DBE/TiCl4 mole ratios. The effect of DBE on the catalyst crystalline forms, determined by X-ray diffraction, was exa mined. The results show that a suitable amount of DBE leads to the formatio n of delta-TiCl3 with high activity and enhanced stereoselectivity. (C) 199 9 Elsevier Science Ltd. All rights reserved.
