Patent ID: 8476392

Claim:
An ethylene alpha-olefin copolymer having: a. a density D of 0.927 g/cc or less; b. a melt flow index I 2 , from 0.1 to 80 g/10 min; c. a molecular weight distribution from 1.5 to 5.0; d. a peak melting temperature T max second melt satisfying the following relation: T max second melt >D* 398−245; e. a T 75 −T 25 value of greater than 20, wherein T 25 is the temperature at which 25 mass % of the eluted polymer is obtained and T 75 is the temperature at which 75 mass % of the eluted polymer is obtained in a TREF experiment; and f. a M 60 /M 90 value of greater than 1, wherein M 60 is the molecular weight of the polymer fraction that elutes at 60° C. and M 90 is the molecular weight of the polymer fraction that elutes at 90° C. in a TREF-LS experiment.
