Abstract:
A CURABLE COMPOSITION WHICH CAN BE CONVERTED INTO CRYALLINE PLASTICS AT AN ELEVATED TEMPERATURE, CHARACTERIZED IN THAT IT CONTAINS LONG-CHAIN POLYAMIDE-DICARBOXYLIC ACIDS OF THE FORMULA
HOOC-A-COOH
WHERE A REPRESENTS A POLYAMIDE RESIDUE WHICH CONTAINS AT LEAST 2 CARBOXYLIC ACID AMIDE GROUPS AND IN WHICH BRANCHED OR LINEAR ALKYLENE AND/OR ALKENYLENE RESIDUE AL. TERNATE WITH THE CARBOXYLIC ACID AMIDE GROUPS, AS WELL AS DIEPOXY COMPOUNDS AND, IF DESIRED, ALSO ANTIOXIDANTS, AND IN WHICH FOR EVERY EPOXIDE GROUP EQUIVALENT 0.7 TO 1.2, PREFERABLY 0.9 TO 1.0 EQUIVALENT OF CARBOXYL GROUPS IS PRESENT.
