Claim Text:
1. A hot melt sealant composition for use as an edge sealant in an insulated glass window unit, consisting essentially of: a. about 2% to 50% by weight of a polyolefin polymer which is made by metallocene catalyzed polymerization; b. about 5% to 50% by weight of an amorphous poly-alpha-olefin polymer; c. about 2% to 25% by weight of an A-B-A styrenic block copolymer; d. about 2% to 25% by weight of an non-metallocene catalyzed ethylene-based copolymer, said non-metallocene catalyzed ethylene-based copolymer comprising an ethylene vinyl acetate copolymer or terpolymer having a vinyl acetate content of 14% to 50% by weight and a melt index of less than 400 g/10 minutes; e. about 10% to 50% by weight of a tackifier; f. about 5% to 25% by weight of a plasticizer; and g. about 0.1% to 3% by weight of an antioxidant stabilizer.
