Polymer prepared by reaction of compounds carrying two or more epoxy groups (reactive epoxides) with curing agents.
Notes:
- The reactive epoxides are commonly prepared by condensation of (chloromethyl)oxirane (commonly called epichlorohydrin) with a di- or multi-functional acid, alcohol, amine, or phenol, most often with 4,4′-(propane-2,2-diyl)diphenol (bisphenol A) to give in this case:
- The reactive epoxide is cured by reactions with a di- or higher-functional amine, carboxylic acid, anhydride, or dicyandiamide (i.e., cyanoguanidine).
- A reactive epoxide or a mixture of reactive epoxides, and also its admixture with curing agent or agents, is usually referred to as an epoxy resin, particularly in a public (popular) use and technological practice. Use of the term "epoxy resin" for a cured epoxide is discouraged; it should be named "epoxy polymer".
