Title (EN) CONDUCTIVE POLYMER-MALEIMIDE BLENDS AND METHOD OF PRODUCING SAME
(FR) MELANGES CONDUCTEURS DE POLYMERE-MALEIMIDE ET LEUR PROCEDE DE PRODUCTION
Abstract:
(EN) Solution blending of (a) a conductive polymer containing carbon-nitrogen linkages, such as polyaniline, having an organic group or an inorganic group, e.g., derived from an anhydride or an aromatic multisulfonic acid, covalently linked to nitrogen atoms of the polymer and (b) a maleimide, particularly a bismaleimide, e.g., the bismaleimide prepared by reacting 1,3 bis (3 aminophenoxybenzene) with 2 units of maleic anhydride, or a bismaleimide terminated oligomer, in a suitable solvent. On removal of solvent and heating to cure the bismaleimide, a continuous phase blend of the conductive polymer and the bismaleimide is formed, having good electrical conductivity and strength. The solution blend can be applied as a coating on a substrate or can be processed to a powder which can be compressed into parts. The conductive blend can be melted and cured without the evolution of volatiles.
(FR) On décrit un mélange en solution se composant (a) d'un polymère conducteur comportant des liaisons carbone-azote, tel que la polyaniline, et ayant un groupe organique ou un groupe inorganique, dérivé par exemple d'un anhydride ou d'un acide multisulfonique aromatique, qui est lié par covalence à des atomes d'azote du polymère et (b) d'un maléimide, notamment un bismaléimide, par exemple un bismaléimide préparé par la réaction de 1,3 bis (3 aminophénoxybenzène) avec deux unités d'anhydride maléique, ou un oligomère à terminaison bismaléimide, dans un solvant approprié. Lorsqu'on enlève le solvant pour chauffer jusqu'à cuisson le bismaléimide, un mélange à phase continue de polymère et bismaléimide conducteur se forme, présentant une bonne conductivité électrique et une bonne solidité. On peut appliquer ledit mélange en solution comme revêtement sur un substrat ou le traiter pour en faire une poudre que l'on peut comprimer en parties. On peut faire fondre et cuire le mélange conducteur sans produire des substances volatiles.
