Polyamides from heptadecane dicarboxylic acid and heterocyclic polyamine

Abstract

Abstract 1. A POLYAMIDE RESIN CONSISTING ESSENTIALLY OF THE POLYMERIC CONDENSATION PRODUCT OF SUBSTANTIALLY EQUIVALENT AMOUNTS OF (1) AN ALIPHATIC DICARBOXYLIC ACID COMPONENT CONSISTING ESSENTIALLY OF (A) AN ISOMERIC MIXTURE OF 1,8- AND 1,9-HEPTADECANE DICARBOXYLIC ACIDS AND (B) OIXTURES OF (A) WITTH A CODICARBOXYLIC ACID OF THE FORMULA R1-OOC-(R'')M-COO-R1 WHEREIN R'' IS A DIVALENT ALKIPHATIC GROUP HAVING 1 TO 12 CARBON ATOMS, R1 IS HYDROGEN OR AN ALIPHATIC HYDROCARBON GROUP HAVING UP TO 8 CARBON ATOMS, AND M IS 0 OR 1, SAID CODICARBOXYLIC ACID BEING PRESENT IN SAID MIXTURES IN AN AMOUNT UP TO 9 EQUIVALENT PARTS PER EQUIVALENT PART OF HEPTADECANE DICARBOXYLIC ACID, AND (2) A DIAMINE OR POLYAMINE COMPONENT CONSISTING ESSENTIALLY OF (A) AT LEAST ONE HETEROCYCLIC DIAMINE OR POLYAMINE SELECTED FROM THE GROUP CONSISTING OF (I) AMINES OF THE FORMULA X-N=A=NH AND (II) AMINES OF THE FORMULA 2-R5,3-R4,3-(H2N-(CH2)N-)-PIPERIDINE WHEREIN A IS -(CH(-R)-CH(-R))- -(CH(-R)-CH(-R)-CH(-CH(-R)-CH(-R))2-R2 -(CH(-R)-CH(-R)-CH(-CH(-R)-CH(-R))2-R3 X IS HYDROGEN OR-R"NH2 AND R" IS ALKYLENE HAVING 1 TO 6 CARBON ATOMS; R2 IS ALKYLENE HAVING 1 TO 8 CARBON ATOMS; R3 IS ALKYLENE HAVING 2 TO 12 CARBON ATOMS; R IS HYDROGEN OR ALKYL HAVING 1 TO 4 CARBON ATOMS; R4 IS HYDROGEN OR ALKYL HAVING 1 TO 4 CARBON ATOMS; R5 IS HYDROGEN OR METHYL; AND N IS 1 OR 3; AND (B) MIXTURES OF (A) WITH AN ALIPHATIC CONDIAMINE OF THE FORMULA H2-N-R6-NH2, WHEREIN R6 IS AN ALIPHATIC HYDROCARBON GROUP HAVING 2 TO 20 CARBON ATOMS, SAID CONDIAMINE BEING PRESENT IN AN AMOUNT UP TO 9 EQUIVALENT PARTS PER EQUIVALENT APART OF HETEROCYCLIC DIAMINE OR POLYAMINE.
