ABSTRACT:
The solvent resistance of polyethersulfone oligomers is enhanced by using difunctional imidophenol end-cap monomers to provide improved crosslinking. The imidophenol monomers include two unsaturated functionalities capable of cross-linking upon thermal or chemical activation. Blends, pregregs, and compositions using the novel end caps are described for linear or multidimensional polyethersulfone oligomers.
