Polyacetylinic oligomers suitable for high-temperature polymer-matrix composites are provided. The polyacetylinic oligomers have the formula: D-A-DwhereinD is an endcap including at least one crosslinking functionality; andA is backbone selected from the group consisting of imidesulfone; ether; ethersulfone; amide; imide; ester; estersulfone; etherimide; amideimide; oxazole; oxazole sulfone; thiazole; thiazole sulfone; imidazole; and imidazole sulfone. At least one ethynyl functional group, however, is incorporated into the backbone such that crosslinking is not only realized at the endcaps but also at the ethynyl groups within the backbone of the oligomer itself.
