Catalyst components for the polymerization of olefins |
| abstract |
A process for the preparation of a solid catalyst component for the homo or copolymerization of olefins which comprises Mg, Ti, halogen and an electron donor selected from cycloalkyl ethers, said process comprising (a) dissolving a Mg based compound and a TiCI 3 based compound in a liquid medium further comprising a cycloalkyl ether and a compound of formula R 2 OH where R 2 is a C 1 -C 20 hydrocarbon group, in which the Ti/Mg molar ratio ranges from 0.1 to 0.5, the cycloalkyl ether/Mg ratio ranges from 1 to 4 and the R 2 OH/Mg molar ratio ranges from 1 to 4; and (b) adding, to the solution coming from step (a), SiCI4 in an amount such that the R 2 OH/SiCI4 molar ratio ranges from 0.5 to 1.5 and maintaining the temperature in the range 50-150°C thereby allowing precipitation of the solid catalyst component particles. |
