Disclosed is a polymer having a silsesquioxane skeleton having a cage structure in the main chain. By introducing the silsesquioxane skeleton into the main chain, the molecular weight and the like can be arbitrarily controlled and the characteristics can be utilized. A polymer obtained by using a silsesquioxane derivative represented by the formula (1-0). In this formula, R 0 is hydrogen, alkyl, cycloalkyl, aryl or arylalkyl, and Y is a group represented by formula (a) or formula (b). In each of these formulas, at least one of X is hydrogen, chlorine or a reactive organic group, and Z in formula (b) is βOβ, βCH 2 β or a single bond. [Selection figure] None |
