Abstract:
1. An aromatic polymer, comprising a repeating unit represented by Formula (I), wherein the polymer has the following properties (A1) and (B1): (A1) the number average degree of polymerization of an acetylated product provided by acetylation of the hydroxyl groups of the polymer is 3 or more, and (B1) at a wavelength where an absolute value of molar ellipticity (degree·cm wherein R represents a hydrocarbon group that may be substituted, a hydrocarbon-oxy group that may be substituted, a hydrocarbon-mercapto group that may be substituted, or a hydrocarbon-amino group that may be substituted; the two R's may be the same or different from each other, or alternatively may bind to each other to form a ring; and the repeating unit represented by Formula (I) has no symmetrical plane that has two binding sites and that is perpendicular for the benzene ring.
