COMPONENTS OF CATALYSTS FOR THE POLYMERIZATION OF ALPHA-OLEFINS |
摘要 |
A process for preparing components of catalysts for the polymerization of alpha-olefins and mixtures thereof with ethylene is disclosed. The process comprises reacting a Ti compound having at least oe Ti-halogen linkage with either (1) a mixture of a hydrocarbyl electron-donor compound ED which does not contain active H atoms and an adduct (a) of a Mg dihalide with at least one hydrocarbyl electron-donor compound AH containing active H atoms, or (2) with an adduct (b) of at least a Mg dihalide with a compound AH and ED defined in (1), adducts (a) and (b) being obtained without co-grinding of the Mg dihalide with compounds AH and ED. |
