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