    • The present invention can provide a polyarylate obtained from a dihydric phenol component and an aromatic dicarboxylic acid component. The polyarylate is characterized in that a compound represented by general formula (C) is used at the molecular end of the polyarylate, and in that a Q value (the amount of molten resin flowing out from a nozzle hole having a diameter of 1 mm and a length of 10 mm using Koka flow tester (high-load-type flow tester) at a temperature of 280°C under a pressure of 15.69 MPa) is 1x10 -2 cm 3 /sec or more:

      wherein in formula (C), Y represents a hydroxyl group or an acid chloride, n is an integer of 1 to 3, and X is

               -R 5 ,

               O-R 5 ,



      wherein each R 5 represents a branched or unbranched alkyl group having 5 to 20 carbon atoms.
    • 本发明可以提供由二元酚组分和芳族二羧酸组分获得的聚芳酯。 该多芳基化合物的特征在于,在聚芳酯的分子末端使用由通式(C)表示的化合物,并且Q值(从直径为1mm的喷嘴孔流出的熔融树脂的量 (高负荷型流动试验机),在温度280℃,压力15.69MPa下,长度10mm)为1×10 -2 cm 3 /秒以上。式(C)中,Y表示 羟基或酰氯,n是1至3的整数,X是-R5,O-R5,其中每个R5表示具有5-20个碳原子的支链或无支链烷基。
