Abstract: AN INERT THERMOPLASTIC AND ELASTOMERIC MATERIAL CAPABLE OF CURING HAS BEEN PROVIDED FOR PREPARING MOLDED ARTICLES NECESSITATING REWORKING. THIS INERT ELASTOMERIC MATERIAL IS DERIVED FROM NITROSO POLYMER AND IS PREPARED BY CURING, AT ELEVATED TEMPERATURE, A COMPOSITION CONSISTING OF A NITROSOTERPOLYMER AND MAGNESIUM OXIDE. A REPRESENTATIVE NITROSOTERPOLYMER CONSISTS OF A POLYMER DERIVED FROM TRIFLUORONITROSOMETHANE, TETRAFLUOROETHYLENE, AND A NITROSOFLUOROCARBOXYLIC ACID OR AN ESTER OF THE CARBOXYLIC ACID. THE NITROSO MONOMER AND/OR NITROSOFLUOROCARBOXYLIC ACID OR ESTER, SUCH AS NITROSODIFLUOROACETIC ACID METHYL ESTER MAKE UP 50% ON MOLE BASIS OF THE MONOMERIC COMPONENTS, THE NITROSOCARBOXYLIC ACID OR ITS ESTER BEING ABOUT 0.5 TO 2% OF THE TOTAL NITROSO COMPONENT BECAUSE OF ECONOMICAL REASONS. BEFORE THE ESTER COMPONENT CONTAINING POLYMER CAN BE USED, THE ESTER MUST BE HYDROLYZED TO THE FREE ACID. AN ELASTOMERIC NITROGEN TETROXIDE STORAGE BLADDER IS A REPRESENTATIVE MOLDED ARTICLE PREPARED FROM THE CURABLE, THERMOPLASTIC COMPOSITION.
