Title:
PROCESS FOR PRODUCTION OF POLYHYDROXYIMIDE
Document Type and Number:
WIPO Patent Application WO/2010/123066
Kind Code:
A1
Abstract:
Disclosed is a convenient process for producing a polyhydroxyimide.
Specifically disclosed is a process for producing a polyhydroxyimide, which is characterized by adding at least one compound represented by formula (2) or (3) (wherein R1 to R4 or R5 to R8 independently represent a hydrogen atom, a monovalent organic group, or the like; and m represents a natural number) to a polyhydroxyimide precursor having a repeating structure represented by formula (1) (wherein X represents a tetravalent aliphatic group or an aromatic group; Y represents an organic group containing an aromatic group substituted by at least one OH group; and n represents an integer of 1 or greater), and heating the resulting mixture to a temperature of 50°C or higher to produce a polyimide having a weight average molecular weight of 5,000 to 100,000 in terms of polystyrene as measured by gel permeation chromatography (GPC).
