Phenylquinoxaline monomers of the formula Ar-C 3BOND C-Pq-C 3BOND C-Ar are disclosed, wherein Pq is <IMAGE> wherein X is a single bond, -O-, -S-, -SO2-, -CH2-, -CO-, -OC6H4O-, -OC6H4-C6H4-O-, -OC10H6O- or -OC6H4SO2C6H4O-; and wherein Ar is an aromatic ether or thioether. These monomers can be crosslinked to provide thermoset resins of the formula <IMAGE> wherein Pq and Ar are as defined above and n has a value between 2 and 3.
