Catalysts for the polymerization of olefins, method of preparing the same

摘要

New olefin polymerization catalysts are disclosed which are prepared by mixing (A) the product obtained by contacting (1) A HALOGEN-CONTAINING, OR A HALOGEN FREE, OXYGEN-CONTAINING ORGANIC COMPOUND OF Ti, V or Zr, with (2) A HYDROCARBON-INSOLUBLE SOLID PRODUCT CONTAINING AT LEAST METAL M and halogen and resulting from decomposition of a complex having the formula (I) MX2.nAlRX2.pAlX3 to M dihalide, or to a product containing M dihalide.
