Abstract
Continuous process for the manufacture of high molecular weight polyamides by condensation polymerization of a number which is a diammonium dicarboxylate derived from a diamine of the formula NH2-X-NH2 and a dicarboxylic acid of the formula HOOC-Y-COOH or which is an aminocarboxylic acid of the formula NH 2 -Z-COOH, X denoting a chain of p-methylene groups containing, without being directly bonded with nitrogen, q m- or p-phenylene bonds; And a chain of methylene r groups containing s m- or p-phenylene bonds; Z a chain of t methylene groups containing, without being directly bonded with nitrogen, bonds of u m- or p-phenylene, where p, q, r, s, t, u, are positive integers, q, s, yu, being the same or different, are each zero, 1 or 2; p is at least 6 if q is zero and s is not zero but at least 2 if q is not zero; r is at least 4 if q is not zero and s is zero; the sum of p and r is at least 6 and t is at least 5 if u is zero, but at least 3 if q is not zero; carrying X, Y and Z to alkyl substitution option and containing, also at option, -O- bonds in the chain, assuming that the groups -OO-, -O-CH2-Ny -O-CH2-CH2-CO - are absent, characterized in that the monomer mixed with water is pumped through an elongated zone of reaction, at least 150 meters long, having a diameter according to the flow rate or velocity of the polymer and heated to polymerization temperatures. .
