摘要：<P>PROBLEM TO BE SOLVED: To provide polyamic acid and polyimide oligomers for use in making adhesives and prepreg. <P>SOLUTION: Citraconic anhydride and itaconic anhydride are used as addition cure end terminators in reactions for forming polyamic acid oligomers and polyimide oligomers. The present invention also relates to prepregs and high temperature adhesives made from the resulting oligomers, as well as, high-temperature and low-void-volume composite materials made from the prepregs. <P>COPYRIGHT: (C)2012,JPO&INPIT
