Abstract: The invention relates to a method for the production of a polyamide based on dicarboxylic acids and diamines, wherein a solid mixture is heated in an extruder, the mixture containing a monomer mixture of 50 mol-% of a dicarboxylic acid mixture of 60 to 88 wt.-% of terephthalic acid and 12 to 40 wt.-% isophthalic acid, in which up to 20 wt.-% of the dicarboxylic acid mixture may also be replaced by other dicarboxylic acids, and 50 mol-% of hexamethylene diamine, up to 20 wt.-% of which may be replaced by other C2-30 diamines, using a synchronized twin screw extruder for a dwell time of 10 seconds to 30 minutes to a temperature in the range from 150 to 400°C while removing water vapor, and possibly diamines, through degassing openings.
