Abstract

Foreliggende oppfinnelse er en høytetthetspolyetylensammensetning, fremgangsmåte for fremstilling av denne, og gjenstander laget derav. Høytetthetspolyetylensammensetningen omfatter en etylen alfa-olefin kopolymer som har en tetthet i området 0,935 til 0,952 g/cm3, en smelteindeks (I2) i området 30 til 75 g/10 minutter, et I21/I2 forhold i området 13-35, et Mw/Mn forhold i området 3,5-8. Høytetthetspolyetylensammensetningen har en sprøhetstemperatur på minst mindre enn -20?C. Fremgangsmåten for fremstilling av en høytetthetspolyetylensammensetning ifølge foreliggende oppfinnelse inkluderer de følgende trinn: (1) introdusering av etylen og én eller flere alfa-olefin komonomerer til en reaktor; (2) (ko)polymerisering av etylen i nærvær av de(n) ene eller flere alfa-olefin komonomer(er) i reaktoren; og (3) derved fremstille høytetthetspolyetylensammensetningen.
