摘要： A process for continuous production of copolyamides based on a lactam (I), a diamine (II) and a dicarboxylic acid (III) comprises reacting a mixture (IV) comprising a diamine (II), a dicarboxylic acid (III) and water in a first reaction zone at a pressure in the range from 1.3*105 to 2.5*105 Pa in the entry zone of the reaction zone and at a temperature above the melting point of polymer (V) to a conversion, based on the molar amounts of diamine (II) and dicarboxylic acid (III), of at least 80% to form a polymer (V), reacting a mixture (VI) comprising lactam (I) and water in a second reaction zone at a pressure in the range from 5*105 to 40*105 Pa and at a temperature above the melting point of polymer (VII) to a conversion, based on the molar amount of lactam (I), of at least 80% to form a polymer (VII), then reacting polymer (V) and polymer (VII) with each other in a third reaction zone at a pressure in the range from 1*105 to 1.5*105 Pa in the entry zone of the reaction zone at temperatures above the melting point of polymer (VIII) to form a polymer (VIII), said polymer (VIII) having a 95° C. water extractables content, based on lactam (I), diamine (II) and dicarboxylic acid (III), of not more than 10% by weight, and then extracting the polymer (VIII) with water to obtain the copolyamide.

摘要： A polymer based on a dicarboxylic acid and a diamine is prepared by polycondensation in an extruder, by (a) heating a mixture of a dicarboxylic acid having from 4 to 12 carbon atoms and a diamine having from 4 to 12 carbon atoms, which mixture is solid at room temperature and has a residual moisture content of less than 5% by weight, to a temperature in the range from 150 to 400° C. under autogenous pressure in a contrarotating twin-screw extruder to give a product A, (b) feeding the product A to a corotating twin-screw extruder, with the product A being exposed to a temperature in the range from 150 to 400° C. and residual water present and also water from the polycondensation being removed through the degassing openings, to give a product B, with the proviso that the corotating twin-screw extruder has at least two segments having different pressures.
