Title
(EN) PREPARATION OF IMIDE OLIGOMERS
(FR) PRÉPARATION D'OLIGOMÈRES D'IMIDE
Abstract
(EN)
Reactive extrusion can be used in a continuous, solvent-less preparation of imide oligomers involving two competing reactions among three ingredients, the first reaction between a dianhydride and a diamine and the second reaction between an endcap and the diamine. The imide oligomer can form a composite via conventional production methods or via formation of a film from imide oligomer re-melted in an extruder before being impregnated into tape or fabric.
(FR)
Un processus d'extrusion réactive peut être utilisé dans le cadre de la préparation, en continu et avec moins de solvant, d'oligomères d'imide impliquant deux réactions rivales mettant en jeu trois ingrédients, la première réaction se faisant entre un dianhydride et une diamine et la seconde réaction entre une coiffe terminale et la diamine. L'oligomère d'imide peut former un composite par des procédés de production traditionnels ou par la formation d'un film à partir d'un oligomère d'imide refondu dans une extrudeuse avant d'être utilisé en vue de l'imprégnation d'un ruban ou d'un tissu.
