が好ましく、特に好ましいモノマー組成比としては、ｐ−ヒドロキシ安息香酸、テレフタル酸、4，4’−ジヒドロキシビフェニル（これらの誘導体を含む。）を８０〜１００モル％と、これら以外の芳香族ジオール、芳香族ヒドロキシジカルボン酸及び芳香族ジカルボン酸からなる群から選択される芳香族化合物０〜２０モル％（両者を合わせて１００モル％とする。）である。ｐ−ヒドロキシ安息香酸、テレフタル酸、4，4’−ジヒドロキシビフェニルが８０モル％未満になると、耐熱性が低下する傾向にあり、好ましくない。

As a particularly preferable monomer composition ratio, p-hydroxybenzoic acid, terephthalic acid, 4,4′-dihydroxybiphenyl (including these derivatives) is 80 to 100 mol%, and other aromatic diols, Aromatic compounds selected from the group consisting of aromatic hydroxydicarboxylic acids and aromatic dicarboxylic acids, 0 to 20 mol% (both are 100 mol% in total ) . When p-hydroxybenzoic acid, terephthalic acid , and 4,4′-dihydroxybiphenyl are less than 80 mol%, the heat resistance tends to decrease, which is not preferable.
