Abstract: A process for the continuous preparation of an aqueous solution of a salt of an alkanedicarboxylic acid of 6 to 12 carbon atoms and an alkanediamine of 6 to 12 carbon atoms by reacting the particular alkanedicarboxylic acid with the particular alkanediamine in an aqueous solution of the salt to be prepared. The aqueous salt solution is recycled from a first mixing zone via a transport zone and a second mixing zone into the first mixing zone, liquid alkanediamine and an aqueous solution of alkanedicarboxylic acid are introduced between the first and second mixing zones. Less than the equivalent amount of alkanediamine is introduced, the remaining amount of liquid alkanediamine is added after the second mixing zone, and aqueous salt solution is taken off the first mixing zone at the rate at which it is formed. The salt prepared is used for the manufacture of a nylon.

Abstract: Polyamide contains 0.05-3% esters of amides of 10-20C atom linear alkane mono-carboxylic acids and 1-12C atom aliphatic alcohols or 2-12C atom aliphatic diamines. These products are transparent and glass-clear. As example a mixture of 99.9% polycaprolactam and 0.1% octyl palmitate after extrusion has a relative light transmission value of 35, while threads with 0 and 0.05% additives have values of 9 and 28 respectively.

Abstract: A process for the manufacture of nylons by heating an aqueous solution of a salt of an alkanedicarboxylic acid of 6 to 12 carbon atoms and a diamine of the formula NH2RNH2, where R is alkylene of 6 to 12 carbon atoms or is a radical to a temperature at which a nylon is formed, under superatmospheric pressure and with removal of water. The solution used is an aqueous solution of from 75 to 90 percent strength by weight of a salt of a dicarboxylic acid and a diamine, which solution has been obtained by neutralizing a less concentrated salt solution, which contains an appropriate dissolved excess of the particular dicarboxylic acid, with the corresponding diamine. The nylons obtained are used for the manufacture of moldings.
