    摘要: Heat resistant, shapable, hydroxy and/or alkoxy-substituted polyamides derived from at least one diamine selected from unsubstituted and substituted 4,4'-bis[2-(4-amino-3-hydroxyphenyl)hexafluoroisopropyl)]diphenyl ether 4,4'-bis-[2-(3-amino-4-hydroxyphenyl)hexafluoroisopropyl]diphenyl ether and a dicarboxylic acid or a derivative thereof e.g. its acid halo or ester. The polyamides of the invention may be thermally cured to form polybenzoxazoles of higher heat resistance which are stable to hydrolytic, chemical and radiation attack.The polyamides of the invention may be formed into shaped articles by molding, extrusion and solvent casting processes preferably in the presence of a solvent or diluent and then optionally converted into heat resistant, insoluble polybenzoxazoles. These shaped articles are useful in aircraft, electronic and other commercial applications where heat, chemical and radiation resistance are desired in conjunction with good mechanical and electrical properties.

    摘要: This invention is that of high temperature polyamides containing the hexafluoroisopropylidene group. The high temperature polyamides of the invention and photo or radiation sensitizers provide improved high temperature positive resists which can be developed in aqueous alkaline developer and thermally anneal to form heat resistant, polyoxazole relief structures suitable for use in microelectronic and printing applications. The positive photoresists of the invention have improved solubility in coating solvents and improved photospeed. The polyamides of the invention can be prepared by conventional condensation reactions; e.g. the condensation of a diamine and diacid chloride. In addition the polyamides of this invention provide high temperature protective coatings with superior adhesion properties in applications other than the photoresist area.

    摘要: The present invention provides polyamide-polyimide and polybenzoxazole-polyimide polymers derived therefrom with improved processing and film characteristics having incorporated into the polymeric backbone the polymeric condensation residuum of novel aromatic diamino compounds having the formula: ##STR1## wherein A is selected from the group consisting of SO.sub.2, O, S, CO, C.sub.1 to C.sub.6 alkyl, perfluoroalkyl or perfluoroarylalkyl having from 1 to 10 carbon atoms and a carbon-carbon double bond directly linking the two aromatic groups, and R is selected from the group consisting of hydrogen, hydroxy and C.sub.1 to C.sub.4 alkoxy.The polyamide-polyimide polymers of this invention are prepared by reacting compounds of the above formula, alone or admixed with other aromatic diamines, with one or more aromatic tetarcarboxylic acids or anhydrides thereof. Polybenzoxazole-polyimide derivatives of such polyamide-polyimide polymers are prepared utilizing compounds of the above formula wherein R is hydroxy or C.sub.1 to C.sub.4 alkoxy, and by subjecting the resulting alkoxy or hydroxy-substituted polyamide-polyimide to a dehydrating and cyclizing reaction to form the oxazole linkage which gives rise to polybenzoxazole-polyimide polymer.
