| abstract |
A composition comprising a silicon-containing compound represented by the general formula (1) described in the specification of the present application, a compound in which m is 3 or more in the general formula (2-1) or (2-2) described in the specification of the present application A compound containing at least any one of integers, and a compound represented by the general formula (3) optionally. In general formula (2-1) or (2-2), m is 3 or more based on the total mass of the silicon-containing compounds of general formula (1), (2-1), (2-2) and (3) The total amount of the silicon-containing compound in the integer is more than 0 ppm and 46000 ppm or less. The composition is used for production of a polyimide precursor obtained by copolymerizing a silicon-containing compound, a tetracarboxylic dianhydride, and a diamine. |
