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

摘要

Ethylene polymers having a) a Polydispersity Index of about 2 to about 4; b) a melt index, MI, and Relaxation Spectrum Index, RSI, such that (RSI)(MI0.6) is about 2.5 to about 6.5; c) a Crystallizable Chain Length Distribution Index, Lw/Ln, of about 1.0 to about 9; and d) a density, rho , and a percent haze when fabricated into films such that the percent haze is less than 370 rho -330, are provided. These ethylene polymers advantageously combine superior clarity and toughness with low extractables and enhanced processing ease.
