Phenolic-capped imide sulfone resins |
摘要 |
A cross-linkable oligomer is formed by reacting polysulfone or polyethersulfone compounds holding two amino groups, aliphatic and/or aromatic compounds containing two anhydride groups, and an amino-phenol. The resulting oligomer has a molecular weight between about 800 and 5000, preferably between about 1000 and 2500, and can be coreacted with an aldehyde and thermally cross-linked to form a cured, thermally stable, solvent-resistant product. The curing reaction mixture preferably also includes a promotor.
