Japanese Patent JP6759682
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide aromatic polyketone which has excellent heat resistance and transparency, is excellent in elongation when a film is formed, and can suppress occurrence of cracks of the surface of a thick film even when the thick film is formed.SOLUTION: Aromatic polyketone has at least one structural unit selected from alkoxy-substituted biphenyl and its derivative unit (1), alkoxy-substituted biphenyl ether or an alkoxy-substituted biphenyl derivative unit (2) connected with a divalent alkylene group, and biphenyl ether and its derivative unit (3), in the molecule; tris(alkoxy-substituted phenyl)benzene and its derivative unit; and a structural unit represented by a structural unit represented by formula 6. In formula 6, Y represents a divalent hydrocarbon group having a saturated alicyclic hydrocarbon skeleton.SELECTED DRAWING: None
