FIELD: chemistry.
SUBSTANCE: invention relates to polyethylene, having density of more than about 0.930 g/ml, which during extrusion at temperature of 590 °F (310 °C) to 645 °F (341 °C) with subsequent application on substrate at rate of 300 feet/min (91 m/min) to 1000 feet/min (305 m/min) has an unevenness of edge from 0 inch/side (0 cm/side) to 2.5 inches/side (6.4 cm/side) and narrowing of less than 3.0 inches/side (7.6 cm/side).
EFFECT: invention discloses novel polyethylene compositions and methods for production and use thereof.
