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.
