    Abstract: A pre-polymerized catalyst component for the polymerization of olefins made from or containing (a) a solid catalyst component made from or containing Ti, Mg, and a halogen and optionally, a bidentate electron donor compound (BE) in an amount such that the molar ratio (BE)/Ti ranges from 0 to 0.3, and (b) an ethylene (co)polymer in an amount ranging from 0.1 g up to less than 30 g per g of the solid catalyst component, and having an intrinsic viscosity, measured in tetraline at 135° C., of at least 3.0 dL/g, wherein the pre-polymerized catalyst component has a porosity measured by mercury method in the range 0.1 to 1 cm3/g.

    Abstract: The present technology relates to a pre-polymerized catalyst component for the polymerization of olefins, characterized by a non-stereospecific solid catalyst component comprising Ti, Mg and a halogen and an amount of a (co)polymer of an alpha-olefin CH2═CHR1, where R1 is a C1-C12 hydrocarbon group ranging from 0.1 to 500 g per g of said solid catalyst component. In some embodiments, the (co)polymer is characterized by an isotacticity, expressed in terms isotactic pentads, of higher than 60 molar % and an intrinsic viscosity, measured in tetraline at 135° C., of at least 1.0 dL/g.

    IPC: C08F110/06 ,  C07F7/28

    Abstract: A solid catalyst component which exhibits high activity and stereospecificity in the polymerization of olefins made from or containing Mg, Ti and an electron donor of formula (I) where R and R1 are selected from the group consisting of C1-C20 hydrocarbon groups, C6-C14 aryl or alkylaryl groups hydrocarbon groups, optionally containing a heteroatom selected from the group consisting of halogens, P, S, N, and O; R2 to R11 groups, equal to or different from each other, are hydrogen, halogen or C1-C15 hydrocarbon groups which can be optionally fused together to form one or more cycles with the proviso that R6 and R11 cannot join together to form a phenyl ring.

    Abstract: The present disclosure relates to a solid catalyst component for the polymerization of olefins comprising Mg, Ti and an electron donor of the formula (I): where each Q is a group —COOR1, in which R1 is selected from C1-C15 hydrocarbon groups, optionally containing a heteroatom selected from the group consisting of halogens, P, S, N and O; or a group —CON(R2)2, in which R2 groups, equal to or different from each other, are hydrogen or R1 groups which can be fused together to form one or more cycles, and A is a bivalent bridging group with the proviso that the Q groups cannot be simultaneously a group —COOR1 or —CON(R2)2.
