Abstract
A solid catalyst component for the polymerization of olefins made from or containing Mg, Ti, halogen and an electron donor of formula (I) or (II) When activated with an aluminum alkyl and optionally an external electron donor, solid catalyst component can give high activity and stereospecificity in the polymerization of olefins.
Claims15
A solid catalyst component for the polymerization of olefins comprising:
- (i) Mg,
- (ii) Ti,
- (iii) halogen,
- (iv) and an electron donor of formula (I) or (II)
- in which
- R1 and R2, independently, are hydrogen or C1-C15 hydrocarbon groups;
- X is a —OR3 or a —NR4R5 groups in which R3 is selected from C1-C15 hydrocarbon groups, optionally containing a heteroatom selected the group consisting of halogens, P, S, N, O and R4-R5 groups, independently, are hydrogen or R3 groups which are optionally fused together to form a cycle;
- R8-R10 groups are independently hydrogen or a C1-C20 hydrocarbon radicals, optionally substituted with heteroatoms selected from the group consisting of halogens, P, S, N, O and Si, which are optionally fused together to form one or more cycles;
- R15 to R16 groups, which are the same or different from each other, are hydrogen or R3 groups which are optionally fused together to form one or more cycles, n is an integer from 0 to 2;
- and
- R11-R14, independently, are selected from hydrogen, halogens or C1-C15 hydrocarbon groups optionally substituted with heteroatoms selected from the group consisting of halogens, P, S, N, O and Si.
