ABSTRACT:
The present invention is a polymer obtained by using a silsesquioxane derivative represented by formula (1-0). In the formula R0each independently represents hydrogen, alkyl, aryl or arylalkyl, and Y each represents a group represented by formula (a) or formula (b). In each of formula (a) and formula (b), at least one of X represents hydrogen, chlorine or a group having one of —CH═CH—, —C≡C—, —OH, —COOH, —COO—, 2-oxapropane-1,3-dioyl, oxiranyl, oxiranylene, oxetanyl, oxetanylene, 3,4-epoxycyclohexyl, —SH, —NH— and —NH2, and in formula (b), Z represents —O—, —CH2— or a single bond.
