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

摘要

Ethylene polymers having a Polydispersity Index of about 2 toabout 4; a melt index, MI, and Relaxation Spectrum Index, RSI, suchthat (RSI)(MI0.6) is about 2.5 to about 6.5; c) a Crystallizable ChainLength Distribution Index, Lw/Ln, of about 1.0 to about 9; and d) adensity, ?, and a percent haze when fabricated into films such that thepercent haze is less than 370? - 330, are provided. These ethylenepolymers advantageously combine superior clarity and toughness withlow extractables and enhanced processing ease.
