Abstract

Procédé de production par une polymérisation en suspension d'un copolymère de composé de cyanure vinylique et de composé vinylique aromatique, d'une composition essentiellement uniforme et d'une teneur en composé de cyanure vinylique de l'ordre de 50 à 85% en poids, ce procédé comportant 3 étapes caactéristiques la première ayant trait au chargement initial des composés monomères la seconde à l'amorçage de la réaction de copolymérisation et la troisième à la réaction de copolymérisation.
