Patent ID: 6992131

Claim:
An adhesive comprising: (a) a copolymer comprising butene, at least 40 mol % propylene, and from 0 to 30 mol % of a termonomer selected from the group consisting of ethylene and C 5 to C 20 linear, branched or cyclic alpha olefins, wherein the copolymer has (i) a weight average molecular weight of 100,000 or less; (ii) a number average molecular weight of 20,000 or less; (iii) an Mw/Mn of 5 or more; and (iv) a viscosity of 8000 mPa.s or less at 190° C.; (b) a hydrocarbon resin; and (c) a polypropylene that is not tactic and has at least 30% crystallinity having a viscosity of 1500 mPa.s or less at 190° C. or a polypropylene that is tactic and has a viscosity of 1500 mPa.s or less at 190° C. provided that if the tactic polypropylene is not present, then the hydrocarbon resin comprises a cyclopentadiene-based hydrocarbon resin.
