Abstract
AbstractOligomers end‐capped by groups capable of thermally induced polymerization have found wide applications in advanced structural composites and adhesives. The styrene‐terminated polysulfone reactive oligomers described in this paper represent an example of such thermosetting systems. The advantage of these compounds, over high molecular weight polysulfone resin, lies in their easier processing and improved solvent resistance. This paper addresses the properties of the neat oligomer as a function of initial molecular weight and those of the resulting cured resin as well as a complete characterization of the curing reaction. Furthermore, a comparison will be made between these oligomers and the better known acetylene‐terminated sulfone oligomers.
