An aliphatic ketone polymer comprising a unit represented by the following formula (1), the unit represented by the following formula (2), and a unit represented by the following formula (3) or (4). (In the formulae, R 1 to R 10 may be the same or different and each represents hydrogen, an optionally halogenated C 1-20 hydrocarbon group, halogeno, hydroxy, ester, alkoxy, cyano, imide, silyl, or a group selected from the group consisting of C 1-20 hydrocarbon groups substituted by a functional group selected among hydroxy, ester, alkoxy, cyano, imide, and silyl, provided that R 2 and R 8 may be bonded to R 3 and R 9 . respectively, to form a monocycle or polycycle; and n 1 , n 2 , and N 3 satisfy 1≤n 1 ≤20, 1≤n 2 ≤35,000, and 1≤n 3 ≤40,000.) |
