ABSTRACT:
The present invention provides a series of easily processable poly(ether-imide)s that are organic-soluble and afford low dielectric constants of films, their organic solutions and their manufacturing process. The poly(ether-imide)s is prepared from a dianhydride and a diamine, wherein the diamine is a diamine having tert-butyl group, i.e. 2,6-di-tert-butyl-4-(4-aminopheny)-1-(4-aminophenoxy)benzene the present invention is also direction to synthesis of this special diamine.
