FIELD: chemistry.
SUBSTANCE: described is non-compound polyolefin powder, which is polymodal polyolefin. The polyolefin powder has such particle size distribution that D95 is less than 355 mcm, D5 is at least less than 60 mcm, and (D90-D10)/D50 is less than 1,2, where D95, D90, D50 and D10 are defined as follows: 95 wt %, 90 wt %, 50 wt % or 10 wt % of the polymer particles have diameter which is less than D95, D90, D50 and D10, respectively. The invention also describes a method of obtaining non-compound polyolefin powder.
EFFECT: low content of gels and white spots in the polymer, improved strength and physical properties of the product.
