Abstract: COPOLYMER COMPOSITIONS OF THE AMIDE-IMIDE VARIETY ARE MADE BY POLYMERIZING PRIMARY DIAMINES WITH AZOBENZENETETRACARBOXYLIC ACID DIANHYDRIDE AND AROMATIC POLYCARBOXYLIC ACID ANHYDRIDE COMONOMERS. THE POLYMERS ARE LINEAR, SHAPABLE, HIGHLY-SOLUBLE COMPOSITIONS WHICH AS FORMED CONTAIN AMIDE ACID GROUPS. THE POLYMERS IN DRY POWDER FORM ARE USEFUL FOR COMPRESSION MOLDING AND IN SOLUTION FORM ARE USEFUL FOR ADHESIVE COATINGS, POROUS MATERIAL IMPREGNATING, CASING FILMS, PREPARING FIBERS AND INSULATING COATINGS. THE POLYMERS ARE HEAT-MODIFIABLE CONVERTING TO THE IMIDE FORM AT ELEVATED TEMPERATURES PRODUCING COMPOSITIONS HAVING EXCELLENT SOLVENT RESISTANCE, THERMAL STABILITY AND ELECTRICAL PROPERTIES.

Abstract: TITLE COMPOUNDS ARE NOVEL OIL-SOLUBLE ANHYDRIDES AND THEIR ANALOGOUS DIACIDS. THE ANHYDRIDES ARE OBTAINED BY REACTION OF C30-214 ALKYL-SUBSTITUTED PHENOL WITH 4-ACID CHLORIDE OF TRIMELLITIC ANHYDRIDE WHICH CAN BE READILY HYDROLYZED WITH WATER TO THE ANALOGOUS DIACIDS. THE TITLE COMPOUNDS ARE USEFUL ANTI-RUST AND/OR ANTI-WEAR ADDITION AGENTS FOR LUBRICANTS AND AS INTERMEDIATE REACTANTS WITH ALCOHOLS AND AMINES FOR PREPARATION OF ESTER, AMIDE AND IMIDE DERIVATIVES ALSO USEFUL AS ADDITION AGENTS FOR LUBRICANTS, ESPECIALLY MINERAL OIL BASED LUBRICANTS.
