Abstract

Composition containing a polyethylene powder having: (a) a specific density of 930 kg/m3 or less; (b) a melt index MI2 greater than 0.5 g/10 min; (c) a ratio of HLMI/MI2 of less than 25, where HLMI is high load melt index measured under a load of 21.6 kg; (d) a bulk density of at least 350 kg/m3; and (e) a d50 greater than 500 μm, and absorbed within said powder at least 1 wt % of a liquid additive. The polyethylene powder has a porosity of at least 0.04 cm3/g for pores smaller than 2μm.
