Novel soluble polyimidesiloxanes and methods for their preparation and use

摘要: Substantially fully imidized polyimidesiloxanes which are based on a sulfurdiphthalic anhydride soluble in diglyme gives them particular utility the micro-electronics industry. The polymers prepared from dianhydride, difunctional siloxane monomer and an organic diamine. Diamines can be used to provide asymmetrical structure polyimidesiloxane polymer chain. with functional groups render directly curable. also when reacted unsaturated compound renders products of invention form solutions micro-electronic wire cable coating prepare films, fibers, molded extruded articles.
