Abstract

L'invention concerne un procédé pour réduire la teneur en monomère résiduel dans les polymères d'acrylonitrile. Selon l'invention, on expose les polymeres ou les articles préparés à partir de ceux-ci à des radiations ionisantes à une dose de 0,050-2,0 mégarads. Application : traitement des bouteilles et récipients alimentaires.The invention relates to a method for reducing the content of residual monomer in acrylonitrile polymers. According to the invention, the polymers or articles prepared therefrom are exposed to ionizing radiation at a dose of 0.050-2.0 megarads. Application: treatment of bottles and food containers.
