Bisphenol a epichlorohydrin resin
WebApart from bisphenol-A, other difunctional phenols can be used to react with epichlorohydrin with the aim of producing epoxy resins. The most commonly used is bisphenol-F (see Fig. 5.8). These epoxy resins are produced by using the same method as performed for DGEBA. The DGEBF epoxy resins have lower viscosity and better … 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)

WebEPON™ Resin 862 (Diglycidyl Ether of Bisphenol F) is a low viscosity, liquid epoxy resin manufactured from epichlorohydrin and Bisphenol-F. This resin contains no diluents or modifiers. EPON Resin 862 may be … Epichlorohydrin is mainly converted to bisphenol A diglycidyl ether, a building block in the manufacture of epoxy resins. It is also a precursor to monomers for other resins and polymers. Another usage is the conversion to synthetic glycerol. However, the rapid increase in biodiesel production, where glycerol is a waste product, has led to a glut of glycerol on the market, rendering this process uneconomical. Synthetic glycerol is now used only in sensitive pharmace…
WebThe DGEBA resins are formed when an excess of epichlorohydrin reacts with bisphenol-A in the presence of an alkali such as sodium hydroxide (Figure 3.2 a). The mechanism of epoxy resin synthesis involves a step-growth polymerization. Initially, the hydroxyl anion from sodium hydroxide abstracts a hydrogen atom from the bisphenol-A (Figure 3.2 b).
