ETHYLENE HOMO-OR COPOLYMERS AND METHODS OR PREPARATION THEREOF Russian patent published in 2001 - IPC

Abstract RU 2164231 C2

FIELD: chemistry of polymers. SUBSTANCE: described are new ethylene homo-and copolymers having sevelling degree of at least 1.4, crack resistance under load of at least 55 hours and fluidity index of at least of 0.2 g/10 min. Also described is method of preparation thereof. Ethylene homo-and copolymers have preferable combination of properties which make them especially suitable for treatment by method of extrusion and extrusion to prepare products (e.g.pipes) having superb mechanical properties and especially high crack resistance under load. EFFECT: improved properties of the title copolymers. 14 cl, 7 ex
