Abstract
A hot melt adhesive is provided that has low viscosity, a high softening point, superior heat resistance, and a high degree of adhesive strength and adhesion stability at high temperatures. The adhesives of the invention comprise (A) an amorphous alpha olefin, (B) a crystalline poly-alpha olefin and (C) hydrogenated thermoplastic block copolymer which are copolymers with vinyl aromatic hydrocarbons and conjugated diene compounds. The adhesive is particularly useful in the manufacture of articles including laminations.
