Patent ID: 7402235

Claim:
A mixture comprising A) a copolymer comprising from about 60 to about 85% by weight of units derived from ethylene, and having (a) M w measured by gel permeation chromatography employing polystyrene standard ranging from 70,000 up to 110,000 and (f) SSI≦18; (b) density (D) ranging from about 845 to about 895 kg/m 3 ; (c) M w / M n less than 3; (d) melting point (T m ) measured by differential scanning calorimeter ranging from about 15° C. to about 60° C.; and (e) degree of crystallinity≧15%; and B) an amorphous polymer of one or more olefins selected from the group consisting of ethylene-propylene copolymers and ethylene-propylene-diene copolymers, having 45% to 55% by weight units derived from ethylene, having M w ranging from 130,000 to 400,000 and having degree of crystallinity≦5%.
