Hot Melt Adhesive Having Both High Peel And Tensile Shear Strength

US Patent:
4129607, Dec 12, 1978
Filed:
May 31, 1977
Appl. No.:
5/802079
Inventors:
John H. Kooi - La Grange Park IL
Ralph M. Schure - Darien IL
John M. Brown - Chicago IL
Assignee:
Unitech Chemical Inc. - Chicago IL
International Classification:
C08L 6300
US Classification:
260835
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.

US Patent:
4093675, Jun 6, 1978
Filed:
Jun 26, 1975
Appl. No.:
5/590622
Inventors:
Ralph M. Schure - Darien IL
John H. Kooi - La Grange IL

Assignee:
Unitech Chemical Inc. - Chicago IL
International Classification:
C08L 6702
C08L 6300
C08L 6106
C08L 6120
US Classification:
260835
Abstract:
A polymeric compound having superior thermoplastic adhesive properties is disclosed. The compound is a poly(ester/ether) block copolymer which is extended with an anhydride to introduce carboxyl groups thereinto. Also disclosed are thermoset adhesives having superior properties and which are such carboxylated copolymers that have been crosslinked with a suitable resin.
