Abstract: Crosslinkable, polyaromatic, polyether or polyester oligomers can have glass transition temperatures above 900.degree. F. while exhibiting desirable toughness for aerospace applications and ease of processing. A plurality (i.e. three or more) of generally linear aryl arms extend outwardly like spokes from a central aromatic hub through ether or ester linkages. Each spoke usually includes electronegative linkages, and is capped with one or two crosslinking functionalities (i.e. unsaturated hydrocarbon sites) which may be thermally or chemically activated to complete the advanced composite during curing. Among other methods, linear and multidimensional polyether oligomers are synthesized using nitrophthalic anhydride or halophthalic anhydride, dialcohols, or polyols, diamines, and suitable end caps.
