PROCESS FOR OBTAINING A BIOCOMPATIBLE MATERIAL OF THE POLYAMIDE TYPE

摘要

Polyamide materials for the construction of protheses and surgical sundries are made biocompatible by inducing a superficial hydrolysis by treating such materials, either raw or in the form of shaped articles, with a normal multiple solution of hydrogen chloride. Thrice normal or fourfold normal solutions are preferred and the treatment time being a function of the temperature. At human body temperature (37 DEG C.) a treatment time from 30 to 60 minutes will do.
