ABSTRACT:
An epoxy resin adhesive composition is provided, and a process to prepare this composition. The composition comprises: a modified hydrogenated block copolymer comprising at least one polymeric block containing predominantly monoalkenyl aromatic hydrocarbon monomer units and at least one polymeric block, prior to hydrogenation, containing predominantly conjugated diolefin monomer units. The modified hydrogenated block copolymer being modified with from 2 to about 200 anhydride or dicarboxylic acid groups per modified hydrogenated block copolymer molecule. The functionality is incorporated substantially into that portion of the polymer containing predominantly conjugated diolefin monomer units. The epoxy resin-modified block copolymer blend is held under high shear mixing under conditions sufficient to react an amount of the modified hydrogenated block copolymer functional groups with epoxy groups effective to provide a stable dispersion of the modified hydrogenated block copolymer in the epoxy resin. A curing agent such as an aromatic polyamine is then added.
