A polysulfide material having reactive vinyl end groups and a method of making a vinyl end-capped polysulfide material are described. The vinyl end-capped polysulfide material has potential applications as a sealant, an adhesive, a coating, a caulking, or the like. In a specific example, the polysulfide material may be used as a precursor material for a sealant resin in the manufacturing of an integral fuel tank of an aircraft. An example method for making polysulfide materials includes contacting a vinyl-functionalized aryl halide and/or a vinyl-functionalized heteroaryl halide with dithiols and/or trithiols in the presence of an organic solvent.
