Abstract

Lors du moulage d'articles façonnés tels que des lentilles de contact à partir de mélanges monomères contenant des monomères de silicone et des monomères hydrophiles, on améliore la mouillabilité de l'article résultant par l'utilisation d'un matériau de moulage produit à partir d'une résine comprenant un copolymère d'un alpha, bêta mononitrile à insaturation d'oléfine et au moins un comonomère améliorant l'aptitude au traitement en fusion.
