Patent ID: 6881477

Claim:
A method for producing a polyamide molding compound, which includes the following method steps: a) addition and dissolving of m-xylylene diamine and dicarboxylic acids, which include adipic acid and aromatic dicarboxylic acids, with water and additives in a dissolving chamber and production of a mixture, the sum of aromatic dicarboxylic acids being 2 mol-percent to 15 mol-percent (in relation to the addition of dicarboxylic acids); b) transfer of the mixture into a reaction vessel and polycondensation of the mixture in this reaction vessel; c) granulation of the polycondensate; d) drying of the granulate; wherein the polycondensation is performed at a pressure of at most 10 bar and a temperature of 255° C. to 270° C., the pressure being built up while heating the reaction vessel to 255° C. to 270° C. and—immediately after the mixture has reached the maximum temperature—being reduced to atmospheric conditions while maintaining a temperature of 255° C. to 270° C., and the polycondensation being continued at this temperature and a pressure of less than 800 millibar; the granulate is subjected to an underwater crystallization before drying.
