Poly-(imino(2,5-dialkoxycarbonyl-1,4-phenylene)iminoarylene)
Abstract
Abstract A NEW HIGH POLYMER COMPRISING RECURRING STRUCTURAL UNITS OF THE FORMULA -(2-(R1-OOC-),5-(R2-OOC-)-1,4-PHENYLENE)-NH-(1,4-PHENYL- ENE)-R3-NH- AND ADDITIONALLY RECURRING STRUCTURAL UNITS OF THE FORMULA -(9-(O=),6-(R1-OOC-)ACRIDAN-7,2-YLENE)-R3-NH- IS OBTAINED BY OXIDATION OF HIGH POLYMER COMPRISING RECURRING STRUCTURAL UNITS OF THE FORMULA -(2-(R1-OOC-),5-(R2-OOC-)CYCLOHEXA-1,4-DIEN-1,4-YLENE)- NH-(1,4-PHENYLENE)-R3-NH- WHICH MAY BE OBTAINED FROM A REACTION BETWEEN DIALKYL SUCCINYL-SUCCINATES AND AROMATIC DIAMINES. THE NEW HIGH POLYMER IS A HEAT RESISTANCE BEING CHARACTERIZED BY SPECTROSCOPIC ABSORPTION IR SPECTRA AT THE VICINITIES OF 2.59, 5.92, 6.38, 6.50, 9.10, 9.50, 11.5 AND 12.7U. IT CAN BE USED TO MAKE FILMS, SHEETS, COATINGS FOR METALS AND AS VARIOUS SHAPED MOLDINGS.
