ABSTRACT:
High performance composites can be made from linear or multidimensional oligomer or blends that include unsaturated hydrocarbon crosslinking functionalities linked to a benzenetriyl or pyrimidine radical on the terminal ends of the polymeric backbones of the oligomers. The oligomers are made by condensing benzenetriyl or pyrimidine-based end-cap monomers of the formulas: ##STR1## wherein R.sub.1 =lower alkyl, lower alkoxy, aryl, aryloxy, substituted alkyl, substituted aryl, halogen, or mixtures thereof;
