ABSTRACT:
The physical properties of high performance composites can be tailored by using coreactive oligomer blends to make the composites. The blends include a first oligomer having an unsaturated hydrocarbon end cap and a second oligomer having an amine, hydroxyl, sulfhydryl, or ##STR1## functionality. Upon curing, the oligomers homopolymerize (i.e. addition polymerize) and mutually interlink (i.e. copolymerize) to form composites possessing intermediate properties to those exhibited by the pure oligomers. The coreactive oligomer blends may also include noncrosslinking polymers and other coreactants, as desired. Stiffness or toughness can be increased in thermally stable composites without significant loss of other properties through these coreactive oligomer blends that cure to block copolymers.
