An adhesive composition comprises (a) at least one polymerizable cyanoacrylate monomer, (b) 0.1 to 10% by weight of a polymerizable acrylate ester e.g. allyl methacrylate and (c) 0.1 to 20% by weight of a maleimide derivative of formula <IMAGE> wherein R<7> and R<8> are from alkyl, cycloalkyl, aralkyl or arkaryl. The compositions may polymerize with ring-opening of the maleimide. They have excellent hot strength properties for long periods at 121 DEG C (250 DEG F) or more. |
