Abstract
Adhesive compositions are described comprising at least an arylaliphatic olyimide with ether chain formations, obtained by the polycondensation reaction of a tetracarboxylic aromatic acid or of one of its derivatives with at least two primary diamines, one of these diamines consisting of a polyether chain ending with the two amine functional groups and at least an epoxy resin possessing more than one epoxy group per molecular. These adhesive compositions can be used particularly for the gluing of films of polymers to thin metal sheets.
