Title (EN) INJECTION MOLDABLE AMIDE-IMIDE COPOLYMERS AND TERPOLYMERS
(FR) COPOLYMERES ET TERPOLYMERES D'AMIDES-IMIDES MOULABLES PAR INJECTION
Abstract: front page image
(EN)Novel copolymers and terpolymers of the amide-imide type are prepared from tricarboxylic acid anhydride compounds, N,N'-diacylated diamines, N-acylated diamines, and primary diamines. These copolymers and terpolymers are useful for preparing injection molded articles of superior properties. A novel process for the manufacture of amide-imide copolymers and terpolymers is disclosed wherein the imide, imide-imide, amide, and amide-amide moieties incorporated into the polymer backbone can be controlled by acylating the amine functionality which is to form the amide and amide-amide moieties while reacting directly those diamines with a tricarboxylic anhydride compound which are intended to form the imide and imide-imide moieties.
(FR)Nouveaux copolymeres et terpolymeres du type amides-imides prepares a partir de composes d'anhydrides d'acides tricarboxyliques, diamines N, N'-diacyles, diamines N-acyles et diamines primaires. Ces copolymeres et terpolymeres sont utiles pour la preparation d'articles moules par injection ayant de meilleures caracteristiques. Un nouveau procede pour la fabrication de copolymeres et terpolymeres d'amides-imides est decrit dans lequel, les parties imide, imide-imide, amide, et amide-amide incorporees dans l'ossature polymere peuvent etre commandees par acylation de la fonction amine qui doit former les parties amide et amide-amide tout en faisant reagir directement ces diamines avec un compose d'anhydride tricarboxylique et qui sont destinees a former les parties imide et imide-imide.
