High performance polyester sulfone oligomers are prepared for aerospace applications by condensing mono- or difunctional crosslinkable end caps (i.e. unsaturated hydrocarbons having one or two crosslinking sites) with dicarboxylic acid halides and dialcohols (i.e. diols). Multidimensional oligomers have an aromatic hub from which the polyester chains radiate. Blends of the linear and multidimensional oligomers can be made using compatible, non-crosslinking polymers. Prepregs and composites are formed from the oligomers or blends.
