FIELD: polymers.
SUBSTANCE: present invention generally relates to polyolefin polymers, such as polypropylene homopolymers, which have improved flow properties. The polymer composition according to the invention contains particles of polypropylene homopolymer, which have a particle size D50 from 150 mcm to 3000 mcm, while the polymer particles have a particle morphology in which the particles have a B/L3 from 0.8 to 1.0, and at the same time polymer the composition has a bulk density of 0.42 g/cm3 to 0.60 g/cm3 and the particles include microspheres.
EFFECT: use of the polymer particles of the invention improves process efficiency, reduces waste, and provides ease of transport and handling of polyolefin polymers.
