摘要： A process for continuously preparing copolyamides from lactams and salts of diamines and dicarboxylic acids, in which lactams together with salts of diamines and dicarboxylic acids are passed from the top downward through a vertical polymerization tube at polyamide-forming temperatures, which comprises a) intensively mixing an aqueous solution of lactams with salts of diamines and dicarboxylic acids under elevated pressure which is greater than the vapor pressure of the mixture which arises in a mixing apparatus at a temperature of from 80 to 300° C., b) feeding the mixture thus obtained to a heated helical tube evaporator in which a liquid phase and a vapor phase form at a temperature of from 140 to 300° C., a stream of water vapor and/or inert gas also being introduced into the mixture if appropriate upstream of the helical tube, c) removing the vapor phase formed in stage b) from the liquid phase and separating it in a column into water vapor and into organic components comprising diamines, dicarboxylic acids and lactams, and recycling the organic components into the polymerization, d) passing the liquid phase from the helical tube of stage b) mixed with the organic components of stage c) from the top downward through a vertical polymerization tube at polyamide-forming temperatures to obtain a copolyamide.

摘要： Disclosed is a method for producing a polyamide containing titanium dioxide pigments. Said method is characterized by the fact that titanium dioxide pigments are dispersed in an initial mixture containing water and caprolactam by means of a device comprising a dispersion chamber, a disk-shaped rotor that is disposed inside said dispersion chamber, a stator that is provided with radial openings, is arranged within the dispersion zone of the dispersion chamber, and is connected to the rotor, a substance inlet located on each side of the rotor, preferably with a respective axial duct section such that the two flows of substance are combined in the peripheral edge area of the rotor disk, and a product outlet which is placed on the outer edge of the dispersion zone of the dispersion chamber, by feeding the titanium dioxide pigments to the dispersion chamber through one of said substance inlets while feeding the initial mixture containing water and caprolactam to the dispersion chamber through the other of said substance inlets, whereby a product mixture containing water, caprolactam, and the used titanium dioxide pigment is obtained via the product outlet, and the product mixture is polymerized so as to obtain a polyamide containing titanium dioxide pigments. Also disclosed are polyamides obtained according to the inventive method and the use of such polyamides as a masterbatch.
