The invention relates to a method for mutually adhering a first moulded article of an at least partially vulcanized rubber polymer and a second moulded article of a polymer. The method comprises at least the steps of providing a first moulded article of a rubber polymer which comprises a compound containing carboxylic acid anhydride; providing a second moulded article of a polymer; providing an adhesive composition comprising at least a polyisocyanate, a polyol and a catalyst; arranging an adhesive layer of the adhesive composition on the surface for adhesion of at least one moulded article; bringing the surfaces for adhesion together under pressure; and polymerizing at least the adhesive layer at a suitable temperature.
