摘要
A catalyst system of such high efficiency that the purification of the polymer can be dispensed with is obtained by first reacting a magnesium halide with an electron donor and/or a cyclopolyene, bringing the product obtained into contact with a TiCl3-containing compound and using a stereoregulator. The system has a high stereospecificity whereby the proportion of atactic polymer is kept low. No excess amount of transition metal halides is required and the polymer obtained has uniform coarse particles and a very low halogen content.
