WebThe most widely used epoxy prepolymer is made by condensing epichlorohydrin and bisphenol A (2,2′-bis (4-hydroxyphenyl)propane). The degree of polymerization of prepolymer 1-20 may be varied to produce liquids (as when x =0) or solids which soften at temperatures up to about 140°C (at x =14). (1-8) WebBisphenol A is mainly used to manufacture epoxy resins by the reaction with epichlorohydrin in the presence of caustic soda at 40 to 60 °C. This yields resins with a molecular weight between 450 and 4000. The molecular weight of the resins increases as the epichlorohydrin/bisphenol A ratio falls. [Pg.160]
