Patent ID: 7439306

Claim:
A method for preparing a polyethylene composition, comprising: blending at least a first polyethylene component having a first density and first Vicat softening point and a second polyethylene component having a second density and second Vicat softening point, wherein: the first density is greater than or equal to 0.910 g/cc and the second density is less than 0.910 g/cc; a difference between the first density and the second density ranges from about 0.01 g/cc to about 0.11 g/cc; the polyethylene components are blended in an amount sufficient to provide a Vicat softening point of the blend composition (V 1 ) that is at least 1.5° C. less than a calculated Vicat softening point of a theoretical blend (V 2 ) based on a weight average of the individual polyethylene components; and the Vicat softening point is measured according to ASTM D-1525.
