    摘要: The present invention provides a polyimide having the formula (II) formed by reacting a dianhydride with the diamine having the formula (I). The polyimide provided by the present invention serves as a material for preparing the liquid crystal aligning film, wherein the liquid crystal aligning film could achieve the pre-tilt angle of 88-90° by containing only less than 5% of the diamine having the formula (I), which could highly lower down the manufacturing cost.

    摘要: 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.
