Precursor solutions of silicone copolymer materials made from a siloxane containing a bis-amino aryl ether of a bis-amino thio ether in dialkyl ethers of condensed polyethlene glycols

Abstract From the Canadian patent

Abstract A precursor solution of a copolymer material which is the product of the condensation reaction of an organic diamine with a siloxane containing a bis-amino aryl ether or bis-amino aryl thioether with molar amounts of an organic dianhydride in a solvent which is at least one selected from the group consisting of monoalkyl ethers of ethylene glycol monoalkyl ethers of condensed polyethylene glycol dialkyl, ethers of ethylene glycol, dialkyl ethers of condensed polyethylene glycol and cyclic ethers containing no less than a 5 member ring is suitable for use as a wire coating passi-, vation and/or protective coating for semiconductor devices and the like. A part or all of the organic …
