Bisphenol S is 4,4’-- Hydroxydiphenyl Sulfone, also known as 4,4’-- DISULFONYL diphenol. BISPHENOL S has excellent heat resistance, light resistance and oxidation resistance. Poly (ether sulfone)(PES) engineering plastics with excellent properties can be prepared by the polymerization of bisphenol s alkali metal salt with dichlorodiphenylsulfone. The Composite Resin of polysulfone and polyethersulfone was synthesized by reaction of polysulfone with Bisphenol A and dichlorodiphenylsulfone. Polycarbonate can be synthesized by the condensation of Bisphenol s with phosgene, or by the condensation of Bisphenol a with phosgene. The BISPHENOL s epoxy cured with bisphenol s has better thermal deformation temperature and thermal stability than Bisphenol a epoxy. It can be used to manufacture high temperature structural adhesives, laminates, molding compounds and powder coatings. BISPHENOL S can also be used to modify bisphenol a epoxy to improve product performance. BISPHENOL S can be used in the preparation of Polyester Resin, Phenol formaldehyde resin, polyethersulfone high temperature anti-wear coatings. Bisphenol s can also be used as an additive in a variety of polymeric resins to improve their properties: polyester resin can be added to increase its impact strength; polyurethane resin can be added as plasticizer; The addition of polyvinyl chloride can increase the resistance to UV aging; the addition of Phenol formaldehyde resin or epoxy can be used as a catalyst to accelerate curing.

Bisphenol s epoxy is a new type of epoxy, which has better flexural, compressive strength and thermal stability than traditional bisphenol a epoxy due to the introduction of-SO2-polar group. The glass transition temperature was 40 °c higher than that of epoxy under the same curing conditions. With the rapid expansion of polymer materials, more and more research has been done on epoxy. Rainere, Udog, HeinrichHW and so on synthesized bisphenol s epoxy by two-step method. SYKORAV, Spacek V. J. The low epoxy value of Bisphenol s synthesized by APPL and epoxy affects the application of bisphenol s bonding properties. In view of the above phenomena, the following two methods are available: (1) the BISPHENOL s epoxy is directly synthesized by one-step precipitation method using base as catalyst, and the chemical stability and thermal stability of the epoxy obtained by this method are good, (2) the Phase-transfer catalyst one step synthesis of bisphenol s epoxy has the advantages of simple process, high purity, less impurities and high epoxy value, however, the melting point of tetramethylammonium bromide used in this method is more than 300 °C, so the reaction temperature is very high and the reaction time is prolonged, which affects the working efficiency. Therefore, a method of synthesizing bisphenol s epoxy with high yield, high epoxy value, short reaction time and high working efficiency has been developed.
