| abstract |
A composition which contains a silicon-containing compound represented by general formula (1) that is mentioned in the description of the present application, and at least either one of the compounds represented by general formula (2-1) or (2-2) that is mentioned in the description of the present application and wherein m is an integer of 3 or more, and which optionally contains a compound represented by general formula (3). The total amount of the silicon-containing compound represented by general formula (2-1) or (2-2) wherein m is an integer of 3 or more is more than 0 ppm but 46,000 ppm or less based on the total mass of the silicon-containing compounds represented by general formulae (1), (2-1), (2-2) and (3). This composition is used for the production of a polyimide precursor which is obtained by copolymerizing a silicon-containing compound, a tetracarboxylic acid dianhydride and a diamine. |
