    Abstract: A process for the production of basic polyamides compatible with substances capable of being cured to plastics comprises reacting at a temperature of between 100 DEG and 350 DEG C., an o : o 1-octane and/or -nonane dicarboxylic acid which contains as a substituent an aliphatic hydrocarbon radical having at least 8 carbon atoms in a continuous chain with a mixture of (a) an aliphatic polyamine, and (b) an aromatic and/or araliphatic polyamine, said polyamines having at least two primary amino groups in a molar ratio of carboxylic acid to amine of 1 : 1.1 to 1:3. Mono- and other di-carboxylic acids, e.g. acetic, benzoic, stearic, adipic, glutaric, sebacic, a -methyl-glutaric, sebacic, isophthalic and terephthalic acid may be present in the reaction mixture. Specified polyamines are ethylene, trimethylene, tetramethylene, pentamethylene, hexamethylene, decamethylene xylylene and o-, m- and p-phenylene diamine, 1 - amino - 9 - aminomethyloctadecane, 1-amino - 10 - aminomethyloctadecane, diaminocyclohexane, di-(aminomethyl) benzenes, 4 : 41-diamino - di - n - butyl ether, a - aminopyridine, polyamines of the formula H2N-(CH2)m-[NH-(CH2) m]n-NH2 where m is an integer from 2 to 6 and n is an integer from 1 to 4, diethylene triamine, triethylene tetramine, dipropylene triamine and tripropylene tetramine. Monoamines, e.g. ethylamine, stearylamine or aniline may also be present in the reaction mixtures. The products of the invention may be used for curing polyepoxides or precondensed phenol, urea or melamine-aldehyde resins.
