Magnesium dichloride-ethanol adducts and catalyst components obtained therefrom

A catalyst component for the polymerization of olefins comprises Mg, Ti and an electron donor of formula (I), where R1 and R2, independently, are selected from hydrogen and C1-C15 hydrocarbon groups, optionally contain an heteroatom selected from halogen, P, S, N, O and Si, which can be fused togeth...

Zusammenfassung:A catalyst component for the polymerization of olefins comprises Mg, Ti and an electron donor of formula (I), where R1 and R2, independently, are selected from hydrogen and C1-C15 hydrocarbon groups, optionally contain an heteroatom selected from halogen, P, S, N, O and Si, which can be fused together to form one or more closed cycles and A is a bivalent bridging group.
