Title (EN) METHOD FOR MAKING POLYIMIDE
(FR) PROCEDE DE FABRICATION DE POLYIMIDE
Abstract: front page image
(EN)The invention is directed to method for making a polyimide by converting the dianhydride to the ester acid and reacting the ester acid with a diamine. The invention allows for the controlled addition of aliphatic diamines resulting in control of the polyimide properties such as the glass transition temperature, solubility, and melt processability.
(FR)L'invention concerne un procédé de fabrication d'un polyimide par la conversion de dianhydride en acide ester et par la mise en réaction de l'acide ester et d'une diamine. Le procédé de l'invention permet l'addition dirigée de diamines aliphatiques et le contrôle des propriétés du polyimide, telles que la température de transition vitreuse, la solubilité et l'aptitude au traitement en fusion.
