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.
