Document Type and Number:
WIPO Patent Application WO/2017/130703
Kind Code:
A1
Abstract:
A production method for a polyimide molded body that has a repeating unit represented by general formula (1). The production method is characterized in that a polyimide solution that includes at least a solvent and a polyimide that has a repeating unit represented by general formula (1) is spray dried at a temperature that is at or above 50℃ below the boiling point of the solvent. The method makes it possible to efficiently produce a polyimide molded body. (In general formula (1), R1 is a single bond, an ether linkage, a sulfide linkage, a sulfoxy linkage, a methylene group, or an ethylene group, R2 and R3 are each independently a hydrogen atom, a methyl group, or a trifluoromethyl group, and R4 is a tetravalent organic group that includes an aromatic ring, said group being represented by one of the indicated structures.)
