Patent ID: 6919407

Claim:
A blend comprising two or more polymer components in which a first component comprises at least about 60 weight percent of units derived from propylene and at least about 4 weight percent of units derived from a comonomer selected from the group consisting of ethylene and an unsaturated monomer, and is characterized as having at least one of the following properties: (i) 13 C NMR peaks corresponding to a regio-error at about 14.6 and about 15.7 ppm, the peaks of about equal intensity, (ii) a skewness index S ix , greater than about −1.20, and (iii) a DSC curve with a T me that remains essentially the same and a T max that shifts to the left as the amount of comonomer in the copolymer is increased, and a second component comprising a thermoplastic polymer other than the polymer of the first component.
