Abstract
Structural adhesive films are presented which comprise branched or networked polymers which are the reaction product of one or more polyether sulfone polymers, which may include amine-terminated polyether sulfone polymers and/or hydroxy-terminated polyether sulfone polymers, with epoxy-functional chemical species including the reaction product of one or more first polyepoxides with an amine-terminated branched polytetrahydrofuran polymer. The structural adhesive films may possess high strength, holding power and durability in high-temperature applications.
