    • An aromatic polymer, containing a repeating unit represented by Formula (I), and having properties (A1) and (B1): (A1) the number average degree of polymerization of an acetylated product obtained 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−2·dmol−1) per mole of the repeating unit of the acetylated product in a circular dichroism spectrum of the acetylated product reaches maximum in a wavelength range of from 200 to 350 nm, the absolute value is 50,000 or more: wherein R represents a hydrocarbon, hydrocarbon-oxy, hydrocarbon-mercapto or hydrocarbon-amino group that may be substituted; the two R's 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.
    • 含有由式(I)表示的重复单元,具有(A1)和(B1)性质的芳族聚合物:(A1)通过聚合物的羟基乙酰化得到的乙酰化产物的数均聚合度为 3以上,并且在乙酰化产物的圆二色谱中每摩尔乙酰化产物的重复单元的绝对摩尔数椭圆率(度·cm-2·dmol-1)的波长的(B1)达到最大 在200〜350nm的波长范围内,绝对值为50,000以上:其中R表示可被取代的烃,烃 - 氧,烃 - 巯基或烃 - 氨基; 两个R可以彼此结合形成环; 并且由式(I)表示的重复单元没有对称平面,其具有两个结合位点,并且与苯环垂直。
