Patent ID: 8476359

Claim:
A hot melt adhesive composition, comprising a blend of the following ingredients: about 5% to 50% by weight of a glassy poly-α-olefin, said glassy poly-α-olefin having a melting point greater than 100 degrees Centigrade and selected from the group consisting of metallocene catalyzed homopolymers or copolymers of propylene with from 2% to 20% by weight of one or more other α-olefin monomer selected from the group consisting of ethylene and C 4 to C 10 α-olefin monomers; about 5% to 70% by weight of a rubbery polymer, said rubbery polymer selected from the group consisting of ethylene-propylene rubber (EPR), ethylene-propylene-diene rubber (EPDM), butyl rubber, and polyisoprene; about 30% to 65% by weight of a compatible tackifier; about 0% to 3% by weight of a stabilizer; about 0% to 10% by weight of a plasticizer; and about 0% to 50% by weight of a wax, the ingredients of the composition adding up to 100% by weight, and the composition having a viscosity between 2,000 and 100,000 cP at 350° F.
