Explanation

Epoxy resins, also known as polyepoxides are a class of reactive prepolymers and polymers, which contains  epoxide groups. Epoxy resins may be reacted (cross-linked) either with themselves through catalytic homopolymerisation, or with a wide range of co-reactants including polyfunctional amines, acids (and acid anhydrides), phenols, alcohols, and thiols. Examples are - Bisphenol A (BPA), Bisphenol F (BPF), Epoxy phenol novolac (EPN), etc. Examples of polyvinyl resins are - PVA (poly vinyl alcohol), PVAc (poly vinyl acetate), etc.
