The present invention relates to a polyarylene sulfide resin having a constitutional unit represented by the following formula (20):
⁅ S-Ar1-Z-Ar2-S-Ar3b-R2b⁆ (20)
wherein R2b represents a direct bond, -Ar6-, -CO-Ar6- or -C(CF3)2-Ar6-; Ar1, Ar2, Ar3b and Ar6 each independently represent an arylene group optionally having a substituent; Z represents a direct bond, -S-, -O-, -CO- or -C(CF3)2-; wherein Z is a direct bond, -CO- or -C(CF3)2- when Ar1, Ar2 and Ar3b are each a 1,4-phenylene group and R2b is a direct bond; and Z is -S-, -O-, -CO- or -C(CF3)2- when Ar1, Ar2 and Ar3b are each a 1,4-phenylene group, R2b is -Ar6- and Ar6 is a 1,4-phenylene group; when the arylene group represented by Ar3b or Ar6 has a substituent, the substituent is an alkyl group having 1 to 10 carbon atoms, a hydroxy group, an amino group, a mercapto group or a carboxyl group.
本发明涉及一种聚芳基
硫醚
树脂,其组成单元由下式(20)表示:
⁅ S-Ar1-Z-Ar2-S-Ar3b-R2b⁆ (20)
其中 R2b 代表直接键、-Ar6-、-CO-Ar6- 或-C(
CF3)2-Ar6-; Ar1、Ar2、Ar3b 和 Ar6 各自独立地代表可选具有取代基的芳烯基; Z 代表直接键、-S-、-O-、-CO- 或-C( )2-;其中当 Ar1、Ar2 和 Ar3b 各自为 1,4-亚苯基且 R2b 为直接键时,Z 为直接键、-CO- 或-C( )2-;当 Ar1、Ar2 和 Ar3b 各为 1,4-亚苯基,R2b 为-Ar6-,Ar6 为 1,4-亚苯基时,Z 为-S-、-O-、-CO- 或-C( )2-;当 Ar3b 或 Ar6 所代表的芳烯基具有取代基时,取代基为具有 1 至 10 个碳原子的烷基、羟基、
氨基、巯基或羧基。
