Abstract: TRANSPARENT POLYAMIDES RESISTANT TO BOILING ARE PRODUCED BY REACTING AN AROMATIC DICARBOXYLIC ACID (OR AN AMIDE-FORMING DERIVATIVE THEREOF) WITH A DIAMINE HAVING THE GENERAL FORMULA:

H2N-CH(-R1)-R2-CH(-R3)-NH2

WHEREIN R1 IS HYDROGEN OR AN ALKYL GROUP OF 1 TO 4 CARBON ATOMS, R2 IS AN ALKYLENE GROUP HAVING 1 TO 10 CARBON ATOMS IN THE CHAIN OR A PHENYLENE GROUP, AND R3 IS AN ALKYL GROUP OF 1 TO 4 CARBON ATOMS. ABOUT 1 TO 25% BY WEIGHT OF THE REACTANTS CAN BE REPLACED BY CAPROLACTAM. THE PRODUCTS ARE ESPECIALLY USEFUL FOR MAKING TRANSPARENT THIN FILMS.

Abstract: PROCESS OF PRODUCING ESTER RESIN CONTAINING ISOCYANURATE GROUPS AND IMIDE GROUPS IN THE POLYMER CHAIN COMPRISING CONDENSING A POLYALCOHOL WITH A TRICARBOXYLIC ACID OF THE FORMULA:

1,3,5-TRI(R-),2,4,6-TRI(O=)HEXAHYDRO-S-TRIAZINE

WHEREIN R REPRESENTS A MOIETY HAVING THE FORMULA:

(CH3-),(5-(HOOC-),1,3-DI(O=)-ISOINDOLIN-2-YL)PHENYL

CHARACTERIZED BY THE STEP OF FORMING SAID TRICARBOXYLIC ACID BY CONTACTING TRIPHENOLIC URETHANE TRIMERIZED TOLUYLENE DIISOCYANATE AND TRIMELLITIC ACID ANHYDRODE IN A MEDIUM CONTAINING THE POLYALCOHOL, AT A TEMPERATURE AND FOR A TIME SUFFICIENT FOR FORMATION OF SAID TRICARBOXLIC ACID.

Abstract: A PROCESS FOR THE PREPARATION OF POLYETHYLENE TEREPHTHALATE BY THE POLYCONDENSATION OF OLIGOMERIC ETHYLENE TERPHTHALATE. A GLYCOLIC SOLUTION OF TRETHYLAMMONUIM OR TRIPROPYLAMMONIUM GERMANATE IS EMPLOYED AS THE CATALYST IN THE PROCESS. THE CATALYST IS PREPARED BY ADDING THE RESPECTIVE TRIALKYLAMINE TO AN AQUEOUS-GLYCOLIC SLURRY OF GERMANIUM DIOXIDE.

Abstract: Poly-(arylene-triketoimidazolidines) are prepared by reacting approximately diamine amounts of bis- (oxalic acid-monoalkyl ester-monoamide) of an aromatic diamine with an aromatic diisocyanate in a polar organic solvent at an elevated temperature. The polymers melt at about 310* C. up to > 400* C. with decomposition. Organic solvent solutions thereof can be used for the production of high-temperature resistant films and fibers as well as coatings for metals. Wire insulating varnishes can also be prepared therefrom.
