The investigation of phenylene sulfide polymers has been divided into seven areas. These are monomer synthesis, polymerization studies, large scale preparations, physical properties of the linear polymer, chemical properties of the polymer, crosslinking studies, and applications. With improvements in the monomer synthesis and polymerization, one pound batches of polymer can be readily made. Once made, the polymer has a degree of polymerization in excess of 100 and is inert to air up to 300 C. It can be chemically crosslinked to improve its stability at 400 C in air or heat treated to not only improve its thermal and oxidative stability at 400 C but to improve its properties as well. The polymer can form fibers from the melt and be used in coatings and laminates. However, its most thoroughly investigated property is its adherence. Bond strengths up to 2700 psi have been obtained on 17-7 stainless steel. It also adheres well to glass and aluminum.
