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: A process for coupling organic molecules involving the step of irradiating an organic compound with ultraviolet light in the presence of hexachlorobenzene, hexabromobenzene or hexaiodobenzene under an inert gas. The process is useful for producing an intermolecular carbon-to-carbon bond by a hydrogen abstraction mechanism from such compounds as acetic acid, methyl acetate, diethyl ether, and phenyl acetonitrile.

Abstract: Aromatic cyclic thiones are synthesized and a process for preparing them by the thermal conversion of aromatic carboxylic acid anhydride to its aryne form and reaction therewith of carbon disulfide is described. The products are useful as bactericides and as extreme-pressure additives in lubricating compositions.
