Abstract:
The present invention provides a series of easily processable poly(ether-imide)s that are organic-soluble and can afford colorless films, their organic solutions and their manufacturing process. The poly(ether-imide) is prepared from a dianhydride and a diamine, wherein the dianhydride is a bis(ether anhydride) having tert-butyl group, i.e. 1,4-bis(3,4-dicarboxyphenoxy)-2-tert-butylbenzene dianhydride. The present invention is also directed to synthesis of this special dianhydride.
