(EN) PROCESS FOR PRODUCING POLY(METH)ACRYLIMIDE MATERIALS
(FR) PROCÉDÉ DE PRODUCTION DE MATÉRIAUX DE POLY(MÉTH)ACRYLIMIDE
Abstract
(EN)
Disclosed herein is a process for the production of poly (meth) acrylimide materials. Therein, a granulated copolymer of (meth)acrylic acid and (meth) acrylonitrile is prefoamed and imidated by thermal treatment in a single step to provide poly(meth)acrylimide particles.
(FR)
La présente invention concerne un procédé de production de matériaux de poly(méth)acrylimide. À cet égard, un copolymère granulé d'acide (méth)acrylique et de (méth)acrylonitrile est pré-moussé et imidé par traitement thermique en une seule étape pour fournir des particules de poly(méth)acrylimide.
