Abstract:
Provided is a polyester polymer including a repeating unit derived from a dicarboxylic acid compound containing a partial structure represented by the following Formula (C) and a repeating unit derived from a diol compound containing a cyclic structure, in which the partial structure represented by Formula (C) constitutes a portion of the main chain: wherein in Formula (C), RA and RB each independently represent a hydrogen atom or an alkyl group having 1 to 6 carbon atoms; n and in each independently represent an integer from 0 to 2; Cy represents an unsaturated 6-membered or 7-membered ring which may contain a heteroatom; and * and ** each represent a bonding hand, while * may be a bonding hand extending from RA.
