ABSTRACT:
The solvent resistance of polysulfone, polyether sulfone, and polyesters is enhanced by using difunctional end-cap monomers of the present invention to provide improved crosslinking. The imidophenol monomers include two unsaturated functionalities capable of crosslinking upon thermal or chemical activation. Oligomer, oligomer blends, pregregs, and composites using the novel end caps are also described.
