Abstract
A process for the preparation of moulded bodies of thermoplastic polyamides, which comprises intensively mixing a polyamide and a masterbatch, converting the mixture by conventional thermoplast processing to moulded bodies and, before use, conditioning the bodies by contact with ambient moisture or, briefly, with water, in which the masterbatch contains at least 5% by weight of a silane substituted by one, 2 or 3 hydrolysable radicals and a functional group which can undergo a chemical reaction, to form a bond, with amino groups and/or carboxyl groups and/or amide groups in the polyamide chain.
