Abstract:
Polyethylene powder comprising at least one additive having: Melt Flow Index (MFI), measured at 190° C. with a load of 2.16 kg in accordance with standard ISO 1133-1:2011, ranging from 0.1 g/10 minutes to 100 g/10 minutes, preferably ranging from 5 g/10 minutes to 35 g/10 minutes; density ranging from 0.890 g/cm 3  to 0.965 g/cm 3 , preferably ranging from 0.940 g/cm 3  to 960 g/cm 3 ; bulk density ranging from 0.35 g/cm 3  to 0.60 g/cm 3 , preferably ranging from 0.40 g/cm 3  to 0.50 g/cm 3 ; average particle diameter (d 50 ) ranging from 400 μm to 800 μm, preferably ranging from 450 μm to 780 μm. Said polyethylene powder comprising at least one additive can be advantageously used in rotomolding.

Claim (Index 10):
Process for the preparation of a polyethylene powder comprising at least one additive in accordance with  claim 1 , comprising:\n preparing a solution comprising at least one additive, operating at a temperature ranging from 25\u00b0 C. to 50\u00b0 C., at a rotation speed ranging from 1 rpm to 100 rpm, for a time ranging from 10 minutes to 50 minutes; adding said solution to at least one polyethylene powder obtained through gas-phase (co)polymerization, and maintaining the whole under stirring, at a rotation speed ranging from 10 rpm to 100 rpm, at a temperature ranging from 25\u00b0 C. to 50\u00b0 C., for a time ranging from 10 minutes to 60 minutes.
