    Abstract: A process for the preparation of a solid catalyst component made from or containing a Ti compound, a coloring agent and optionally an electron donor on a Mg chloride based support, including step (a), carried out at a temperature ranging from 0 to 150° C., wherein (i) a Mg-based compound of formula (MgClmX2-m).nLB, wherein m ranges from 0 to 2, n ranges from 0 to 6, X is, independently halogen, R1, OR1, —OCOR1 or O—C(O)—OR1 group, wherein R1 is a C1-C20 hydrocarbon group and LB is a Lewis base, is reacted with (ii) a liquid medium made from or containing a Ti compound having at least a Ti—Cl bond in an amount such that the Ti/Mg molar ratio is greater than 3; and an organic coloring agent is present either associated to the Mg-based compound or dispersed in the liquid medium made from or containing the titanium compound.

    IPC: C08F210/16

    Abstract: A process for the continuous solution polymerization including the step of polymerizing a first olefin monomer of formula CH2═CHR1, wherein R1 is hydrogen or a hydrocarbon radical having from 1 to 8 carbon atoms with a second olefin monomer of formula CH2═CHR2, wherein R2 is a hydrocarbon radical having from 3 to 8 carbon atoms, in the presence of a polymerization catalyst and in the absence of an inert solvent, at a polymerization temperature (Tp) satisfying the following relationship: Tp≥Tm+20° C. wherein Tm is the melting temperature of the obtained polymer.

    IPC: C08L23/12

    Abstract: A polypropylene composition made from or containing: A) from 60 to 90 wt %, based upon the total weight of the polypropylene composition, of a fraction insoluble in xylene at 25° C., is made from or containing more than 80% wt of propylene units, and B) from 10 to 40 wt %, based upon the total weight of the polypropylene composition, of a fraction soluble in xylene at 25° C. is made from or containing a copolymer of propylene and ethylene having an average content of ethylene derived units from 30.0 wt % to 55.0 wt %, wherein the fraction when subjected to GPC fractionation and continuous IR analysis for determining the ethylene content of the eluted fractions (GPC-IR analysis), shows that the content of ethylene increases along with the Mw for fractions having Mw higher than the average.
