Abstract:
A polymer composition comprising ethylene interpolymerized with at least one unsaturated comonomer, wherein the composition is characterized as having:a) a melt flow ratio, I10/I2, from 8 to 10.4, b) a Mw/Mn of greater than 4 as determined by gel permeation chromatography, c) a melt index, I2, from 0.1 to 10 gram/10 minutes, d) a composition density less than 0.945 gram/cubic centimeter, and e) based on the total weight of crystallizable polymer portions, a weight percent at the dominant peak temperature above 75Â° C., as determined using crystallization analysis fractionation in the range of 20 to 100Â° C., equal to or greater than the mathematical product of 1.7946Ã—10âˆ’28Ã—10(31.839Ã—composition density) for composition density in grams/cubic centimeter.
