Process for the production of stabilizer concentrate for polyamide

A method of producing a polyamide stabilizer concentrate containing a multiplicity of stabilizer components and a bonding agent, the method comprising homogeneously mixing the stabilizer components and bonding agent in the absence of liquid additives and without any additional heat and compacting the resulting mixture into tablets by subjecting it to a compression force p that heats the mixture to a temperature t.sub.c of at least 40.degree. C. and equal to the wax solidification temperature, t.sub.A, minus 10.degree. to 50.degree. C., wherein

• a) the bonding agent consists of a wax having an alkyl chain of at least 15 C atoms and at least one acid, amide, and/or lower alkyl ester end group and optionally contains a micro-dispersed silicic acid, wherein the wax has a solidification temperature t.sub.A between 65.degree. and 120.degree. C.,
• b) 0.5 to 20 weight % of the stabilizer components, including the micro-dispersed silicic acid, have an average particle size under 2.mu., and the average particle size of the remaining 99.5 to 80 weight % ranges from over 2.mu. to 200.mu., and
• c.sub.1) at least two of the stabilizer components react with one another at a temperature of t.sub.c and a compression force of p while forming intermolecular solid state bridges, and/or
• c.sub.2) at least one of the stabilizer components has a covalent matrix structure and at least one of the stabilizer components has an ionic structure, wherein said stabilizer components having molecular or ionic structures fuse together when subjected to a temperature t.sub.c and a compression force p, so that their crystal structures become compacted.
