Laminated products bonded together with a quinoxaline polymer
Abstract
Abstract POLYMERS CONTAINING RECURRING QUINOZALINE GROUPS WHICH ARE THE REACTION PRODUCTS OF AROMATIC TETRAMINES CONTAINING TWO SETS OF ORTHO-AMINE FUNCTIONS ATTACHED TO THE AROMATIC NUCLEUS AND TETRACARBONYL COMPOUNDS HAVING THE FORMULA: R-CO-CO-R1-CO-CO-R2 WHEREIN R AND R2 REPRESENT A MEMBER SELECTED FROM THE GROUP CONSISTING OF HYDROGEN AND MONOVALENT HYDROCARBON GROUPS, AND R1 REPRESENTS A DIVALENT HYDROCARBON GROUP. THE SALTS OF THE AROMATIC TETRAMINES AND THE HYDRATES OF THE TETRACARBONYL COMPOUNDS ,AY ALSO BE USED TO PREPARE THE POLYMERS. QUINOZALINE POLYMERS CAN BE USED FOR MAKING FILMS, FIBERS AND ADHESIVES AS WELL AS FOR OTHER PURPOSES. LAMINATED ARTICLES BONDED TOGETHER WITH THESE ADHESIVE COMPOSITIONS, SUCH AS HIGH TEMPERATURE METAL LAMINATES ARE ALSO DISCLOSED.
