A polymer represented by the following general formula (I). (In the general formula (I), X 1 , X 2 and X 3 represent an oxygen group element atom. R 1 and R 2 each independently represent a hydrogen atom, an alkyl group having 1 to 18 carbon atoms, and an alkyl group having 2 to 18 carbon atoms. In any of the group consisting of alkenyl and aralkyl, R 3 and R 4 each independently represent an alkyl group with 1 to 6 carbons, an alkenyl group with 2 to 6 carbons, an aryl group, and an aralkyl group In any of the group consisting of radicals, R 5 and R 6 each independently represent a hydrogen atom, an alkyl group having 1 to 6 carbon atoms, an alkenyl group having 2 to 6 carbon atoms, an aryl group, and an aralkyl group. In any of the groups, R 7 represents a hydrogen atom or a methyl group, and R 8 represents a group selected from the group consisting of a hydrogen atom, an alkyl group having 1 to 6 carbon atoms, an alkenyl group having 2 to 6 carbon atoms, an aryl group, and an aralkyl group. Any of the group. n is an arbitrary integer. R 3 , R 4 , R 5 and R 6 are not linked to each other to form a ring structure.) |
