Novel high performance thermosetting polyimides
Meyer, Gerald W.
MetadataShow full item record
Soluble imide thermosetting (reactive) oligomers of controlled moleular weights were synthesized utilizing 3-phenylethynylmdine, 4-phenylethynylphthalic anhydride or phenylmaleic anhydride as the reactive endcapping agents. The phenylethynyl endcapping agents were synthesized by a ppalium-catalyzed coupling reaction in yields greater than 80 % after purification. The polyitmide oligomers were synthesized via solution imidization techniques, using the ester-acid derivatives of various dianhydrides and various aromatic diamines.
