Effect of short chain branching on the blown film properties of linear low density polyethylene

摘要: Three linear low density polyethylene (LLDPE) resins of similar melt index and were synthesized with different comonomers in the Unipol pilot-plant scale reactor. The molecular structure, blown film morphology, strength properties have been comprehensively characterized. dart drop impact LLDPEs increases order ethylene/1-butene, ethylene/1-octene, ethylene/1-hexene copolymers; whereas Elmendorf tear them ethylene/1-hexene, ethylene/1-octene copolymers. mechanical seem to be highly associated length distribution short chain branches and, consequently, lamellar thickness resins. © 1996 John Wiley & Sons, Inc.
