Patent ID: 8853329

Claim:
An adhesive comprising: (i) greater than 30 wt %, based on the total weight of the adhesive, of a pre-blended, degraded polymer system consisting of: (a) 30 to 70 wt % of an elastomeric rubber selected from the group consisting of ethylene-propylene rubber copolymer, ethylene-propylene-diene rubber terpolymer, and mixtures thereof; and (b) 30 to 70 wt % a semi-crystalline olefinic polymer or a blend of semi-crystalline olefinic polymers; (ii) a tackifier; and (iii) an antioxidant; wherein the degraded polymer system has a melt viscosity of less than 50% than the pre-blended, non-degraded polymer at 200° C.; and wherein the semi-crystalline olefinic polymer has a heat of melting from 20 to 95 J/g.
