Patent ID: 8431643

Claim:
An adhesive composition comprising: (i) a polyolefin polymer comprising a propylene content of at least 50 mol % wherein the polyolefin polymer has: (a) a heat of fusion from 2 to 120 J/g; (b) a weight average molecular weight (Mw) from 15,000 to 250,000; (c) a weight average molecular weight/number average molecular weight ratio (Mw/Mn) from about 1.8 to 10; (ii) at least one wax having a weight average molecular weight equal to or greater than about 3000, a viscosity at 140° C. from about 100 mPa·s to about 10,000 mPa·s and a wax softening point as defined by at least one of (A)-(D): (A) mettler drop point as determined by ASTM-D3954-94 greater than 110° C.; (B) congealing point as determined by ASTM D-938 greater than 110° C.; (C) ring and ball softening point as determined by ASTM E-28 is greater than 110° C.; or (D) peak melt temperature as determined by DSC is greater than 110° C.; and (iii) a wax modifier comprising a functionalized polyethylene and a maleated polypropylene.
