Title:
AROMATIC POLYETHER KETONE MOLDED BODY AND PRODUCTION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/210235
Kind Code:
A1
Abstract:
[Problem] To provide a technique capable of further improving the performance of an aromatic polyether ketone molded body. [Solution] This aromatic polyether ketone molded body comprises a main body part and a surface layer part covering the main body part. In both the main body part and the surface layer part, infrared absorption spectra including a peak A appearing in a wave number range of 1,295-1,340 cm-1 and a peak B appearing in a wave number range of 1,265-1,295 cm-1, as measured by an infrared spectrophotometer, are obtained. The ratio A'/B' of the intensity A' of the peak A to the intensity B' of the peak B is higher in the surface layer part than in the main body part.
