    摘要: Novel polyetherimides containing sulfone units such as those derived from bis(3,4-dicarboxyphenyl) sulfone dianhydride, as well as units derived from an ether anhydride such as 2,2-bis[4-(3,4-dicarboxyphenoxy)phenyl]propane dianhydride, may be prepared by the reaction of a mixture of said dianhydrides with diamines such as m-phenylene diamine. The polyetherimides have high thermal stability and solvent resistance.
