Explanation

Epoxy resins, also known as polyepoxides, are a class of reactive prepolymers and polymers which contain epoxide groups. Epoxy resins may react (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.
