Abstract:
A polyolefin nanocomposite material comprising the following components: (A) a crystalline or semi-crystalline polyolefin resin; and (B) a nanosized mineral filler comprising or substantially consisting of a hydrotalcite, wherein the amount of the hydrotalcite is from 0.02 to 6 parts by weight per 100 parts by weight of the nanocomposite material, and the ratio MFR (1)/MFR (2) of the melt flow rate value MFR (1) of component (A) to the melt flow rate value MFR (2) of the polyolefin nanocomposite material is of at least 1.02, charachterized in that - the said polyolefin nanocomposite material includes a compatibilizer - the dispersion of the mineral filler (B) and compatibilizer in the polyolefin resin is produced at shear mixing rates from 30 to 300 sec -1.
Abstract:
Spherical adducts comprising a MgCl 2 , an alcohol ROH in which R is a Cl-ClO hydrocarbon group, present in a molar ratio with MgCl 2 ranging from 0.5 to 5 and less than 5% wt, based on the total weight of the adduct, of a solid inorganic compound selected from oxides or hydroxides of Si, Al, Mg, Ti and mixtures thereof. The catalyst components obtained from the said adducts generate during polymerization a reduced content of broken polymer particles in comparison with the catalyst obtained from adducts not containing the inorganic solid compound.
