POLYIMIDESILICONE RESIN, METHOD FOR PRODUCING THE SAME AND COMPOSITION THEREOF

摘要

PURPOSE: To provide a polyimidesilicone resin containing cyclic siloxane oligomers causing electric contact point troubles in a reduced content, to provide a method for producing the polyimidesilicone resin, and to provide a polyimidesilicone resin composition which contains the polyimidesilicone resin as an active component and exhibits high adhesivity and high reliability to substrates. CONSTITUTION: This polyimidesilicone resin characterized by containing cyclic siloxane oligomers having ten or less silicon atoms in an amount of <= 300 ppm, having a glass transition point of <= 250°C and being soluble in organic solvents. The polyimidesilicone resin is produced from a diaminosiloxane having a cyclic siloxane oligomer content of <= 300 ppm. The polyimidesilicone resin composition comprising 50 to 99 wt.% of the polyimidesilicone resin and 1 to 50 wt.% of an epoxy compound.
