Abstract

Procédé de préparation de matières biocompatibles. Le procédé consiste à soumettre des matières polyamide à un traitement d'hydrolyse superficiel en les faisant réagir avec de l'acide chlorhydrique en solution 3 à 4 fois normale pendant un temps déterminé selon la température, de 30 à 60 minutes à 37 degrés C. Application des matières polyamide ainsi obtenues à la fabrication de prothèses et de sondes chirurgicales.
