Abstract
A solid catalyst component for the polymerization of olefins made from or containing Mg, Ti, Cl and at least an electron donor compound which is the reaction product obtained by bringing into contact a Mg compound and a Ti compound having at least a Ti-halogen bond with an electron donor selected from diphenol derivatives.
Claims15
A solid catalyst component for the polymerization of olefins comprising Mg, Ti, Cl and at least an electron donor compound which is the reaction product obtained by bringing into contact a Mg compound and a Ti compound having at least a Ti-halogen bond with an electron donor selected from diphenol derivatives of formula (I)
- wherein X is a chlorine substituted phenyl group, and Y is selected from hydrogen or 10;
- the R groups, equal to or different from each other, are selected from hydrogen, halogen and C1-C15 hydrocarbon groups, optionally containing a heteroatom selected from halogen, P, S, N, O and Si, which can be fused together to form one or more cycles, and Rr is a C1-C5 aliphatic group.
