Beschreibung
Zusammenfassung:A polyimide silicone resin derived from a diamine including a diaminopolysiloxane and an acid dianhydride, consists of >=50 wt.% siloxane residual group and has an elongation at rapture of >=400% and a modulus of elasticity of =500 N/mm2>. Independent claims are also included for: (A) a polyimide silicone resin solution composition including the inventive polyimide silicone resin and an organic solvent for dissolving the polyimide silicone resin; and (B) a polyimide silicone resin film including the inventive polyimide silicone resin formed on a substrate, i.e., an electrode for electronic component parts or semiconductor devices. Gegenstand der Erfindung ist ein Verfahren zur Herstellung von linearkettigen Copolysiloxanen, bestehend aus Einheiten der allgemeinen Formeln (1) und (2) DOLLAR A [-(R·1·R·2·SiO)¶a¶-] DOLLAR A [-(R·3·R·4·Si-R·7·-SiR·5·R·6·O)¶b¶-R·3·R·4·Si-R·7·-SiR·5·R·6·-]' DOLLAR A deren Endgruppen ausgewählt werden aus Si-H und Si-OH, bei dem (A) Diorganopolysiloxane der allgemeinen Formel (3) DOLLAR A HO-(R·2·R·2·SiO)¶a¶-H DOLLAR A mit (B) Silarylensiloxanverbindungen der allgemeinen Formel (4) DOLLAR A H-[(R·3·R·4·Si-R·7·-SiR·5·R·6·O)¶b¶-R·3·R·4·Si-R·7·-SiR·5·R·6·]-H DOLLAR A in Gegenwart von (C) Übergangsmetallkatalysator umgesetzt werden, wobei in den allgemeinen Formeln (1) bis (4) R·1·, R·2·, R·3·, R·4·, R·5·, R·6·, R·7·, a und b, die in Anspruch 1 angegebenen Bedeutungen aufweisen.
