Title:
AROMATIC POLYETHER COPOLYMER, METHOD FOR PRODUCING AROMATIC POLYETHER COPOLYMER, AND METHOD FOR CONTROLLING CRYSTALLIZATION TEMPERATURE OF AROMATIC POLYETHER COPOLYMER
Document Type and Number:
WIPO Patent Application WO/2022/230943
Kind Code:
A1
Abstract:
An aromatic polyether copolymer which contains a repeating unit represented by formula (1) and a repeating unit represented by formula (2) and has such a property that an integral ratio X represented by the formula (IX) shown below is more than 0% in 1H-NMR spectra. X [%] = \{(C/2)/(A/8+B/4)\} × 100 (IX) (In formula(IX), A represents a value of the integral from a chemical shift of 7.15 ppm to a chemical shift of 7.23 ppm; B represents a value of the integral from a chemical shift of 7.32 ppm to a chemical shift of 7.42 ppm; and C represents a value of the integral from a chemical shift of 7.89 ppm to a chemical shift of 7.93 ppm.)
