Quinoxaline polymers,methods of making same and compositions thereof
Abstract
Abstract POLYMERS CONTAINING RECURRING QUINOXALINE GROUPS WHICH ARE THE REACTION PRODUCTS OF AROMATIC TETRAMINES CONTAINING TWO SETS OF ORTH/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 MAY ALSO BE USED TO PREPARE THE POLYMERS. QUINOXALINE POLYMERS CAN BE USED FOR MAKING FILMS, FIBERS AND ADHESIVERS AS WELL AS FOR OTHER PURPOSES. LAMINATED ARTICLES BONDED TOGETHER WITH THESE ADHESIVE COMPOSITIONS, SUCH AS HIGH TEMPERATURE METAL LAMINATES ARE ALSO DISCLOSED.
