ETHYLENE POLYMERS HAVING SUPERIOR CLARITY, ENHANCED TOUGHNESS LOW EXTRACTABLES AND PROCESSING EASE.

摘要

Ethylene polymers having a Polydispersity Index of about 2 to about 4; a melt index, MI, and Relaxation Spectrum Index, RSI, such that (RST)(MI0.6) is about 2.5 to about 6.5;c) a Cystallizable Chain Length Distribution Index, Lw/Ln, of about 1.o to about 9; and d) a density, (, and a percent haze when fabricated into films such that the percent haze is less than 370p -330, are provided. These ethylene polymers advantageously combine superior clarity and toughness with low extractables and enhanced processing ease.
