The present invention relates to copolymers consisting essentially of [-ether-phenyl-ether-phenyl-carbonyl-phenyl-] and [ether-phenyl-phenyl-ether-phenyl-carbonyl-phenyl-] repeating units and end units, having a reduced melting temperature (Tm) compared to copolymers comprising such repeating units in the prior art. The copolymers of the present invention have crystallinity and have similar glass transition temperatures to prior art copolymers. 本发明涉及基本上由[-醚-苯基-醚-苯基-羰基-苯基-]和[醚-苯基-苯基-醚-苯基-羰基-苯基-]重复单元以及末端单元组成的共聚物，其具有与现有技术中包括这样的重复单元的共聚物相比降低的熔融温度(Tm)。本发明的共聚物具有结晶度并且具有与现有技术共聚物相似的玻璃化转变温度。
