Document Type and Number:
Japanese Patent JP2017132845
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an efficient method for producing a polyimide molding.SOLUTION: The present invention provides a method for producing a polyimide molding having a repeating unit derived from a diamine having a hexafluoropropanol group represented by formula (1). In the method, a polyimide solution at least comprising a polyimide having a repeating unit represented by formula (1) and an amide, ether, halogen or lactone solvent having a boiling point of -50 to 100°C is sprayed and dried at a temperature lower than the boiling point of the solvent by at least 50°C. (Ris a divalent group of a single bond, an ether, a sulfide, a sulfoxy, a methylene, or an ethylene; Rand Rindependently represent H, a methyl or a trifluoromethyl; and Ris a tetravalent group comprising an aromatic ring).SELECTED DRAWING: None
