Abstract:
1. A polymer obtained by reacting a silsesquioxane derivative represented by formula (1-0) with a compound having at least two groups capable of reacting with a reactive group in the silsesquioxane derivative: wherein R 0 each independently represents alkyl, aryl or arylalkyl; in the alkyl, the number of carbon atoms is from 1 to 40, arbitrary hydrogen may be replaced by fluorine, and arbitrary —CH 2 — may be replaced by —O—, or cycloalkylene; in the aryl, arbitrary hydrogen may be replaced by halogen or alkyl having 1-20 carbon atoms; the arylalkyl is constituted by aryl in which arbitrary hydrogen may be replaced by halogen or alkyl having 1-20 carbon atoms, and alkylene in which arbitrary hydrogen may be replaced by fluorine, and arbitrary —CH 2 — may be replaced by —O—, or cycloalkylene; in the alkyl having 1-20 carbon atoms as a substituent of the aryl, arbitrary hydrogen may be replaced by fluorine, and arbitrary —CH 2 — may be replaced by —O—, cycloalkylene or phenylene; R 1 each represents chlorine, or a group defined identically with R 0 ; X independently represents hydrogen, a group defined identically with R 1 , or a group having one of —CH═CH—, —C≡C—, —OH, —COOH, 2-oxapropane-1,3-dioyl, and —NH 2 ; and at least two of X each is hydrogen, or a group having one of —CH═CH—, —C≡C—, —OH, —COOH, 2-oxapropane-1,3-dioyl, and —NH 2 ; with the proviso that where at least two of X each represents a group having —CH═CH— or —C≡C—, a reactive group of the compound, with which the silsesquioxane derivative represented by formula (1-0) is reacted, is a Si—H group.
