| Abstract | The role of ethers in the synthesis of a highly active and stereospecific catalyst for propylene polymerisation was studied. Diisoamyl ether and THF were used as electron donors in the beta-titanium trichloride treatment during the three-step synthesis. Dibutyl ether was employed as a first internal base complexed with TiCl4 and Et2ClAl in isooctane solution in the one-step synthesis. The effects of ethyl benzoate, tributyl phosphate and diisobutyl phthalate as second internal bases on the crystalline modification, activity and stereospecificity of TiCl3 were also investigated. 9 refs. |
