High Temperature Laminating Resins
Abstract
Nitrile-terminated polyimides were prepared by the reaction of benzophenonetetracarboxylic dianhydride, aromatic diamines and meta- orpara- minobenzonitriles. At least two other linkages were necessary per repeating unit to yield a fusible and soluble prepolymer provided the oligomerhad no more than three repeating units. Using sulfone as a solvent theseoligomers could be A- staged with terephthalonitrile N, N'-dioxide to yieldcurable resins. Compressive strength, flexural strength, and modulus datawere obtained for glass cloth laminates. Synthetic techniques were exploredfor preparing acetylene-substituted polyimides.
