Abstract

Process for obtaining polyamides and copolyamides, characterized in that at least one diamine of formula ** formula ** is condensed where R1 and R2, the same or different from each other, can be hydrogen, an aliphatic or aliphatic cyclo radical, R3 and R4, the same or different from each other, they can be aliphatic or cyclic aliphatic radicals, and R5 can be hydrogen, an aliphatic, cyclic aliphatic or aromatic radical, with at least one aliphatic, cyclic aliphatic or aromatic bicarboxylic acid, or its ester salts and chlorides.
