ABSTRACT:
Blends of certain block copolymers and epoxy resins, which have superior thermoplastic adhesive properties are disclosed. The blends are prepared by mixing hydroxy-terminated poly(ester/ether) block copolymers with epoxy resins. These unreacted blends are useful as hot melt thermoplastic adhesives having very high peel strength, high tensile shear strength, creep resistance at elevated temperatures, and good viscosity stability.
