Ethoxyline resin

The epoxide resins (also widely known as epoxy resins and, occasionally, as ethoxyline resins) are characterised by the possession of more than one 1,2-epoxy group (I) per molecule. This group may lie within the body of the molecule but is usually terminal. 

The terms epoxy resin (EP) and ethoxyline resin are used to describe polyphenol derivatives and other compounds which resinify by ring opening of oxirane rings. The polyphenols are typically diphenylolmethane or bis henol A [2,2-bis(4-hydroxyphenyl)propane] the latter diol is obtained by the condensation of phenol and acetone. Bisphenol A, is the most widely used phenol for epoxy resin production.

The epoxy-resin molecule is characterized by the reactive epoxy or ethoxyline groups which serve as terminal linear polymerization points. When crosslinking or cure is accomplished through these groups or through hydroxyls or other groups... 

Epoxy resins are an important class of polymeric materials, characterized by the presence of more than one three-membered ring known as the epoxy, epoxide, oxirane, or ethoxyline group. 

It may be noted that there are various practices with respect to nomenclature in the literature. The epoxy group is also called the epoxide, oxirane or ethoxyline group. Both cross-linked polymers and low molecular weight resin precursors are variously known as epoxies or epoxides. In this chapter, the terms epoxy, epoxy resin and epoxy group are used to indicate cross-linked polymer, precursor and functional group respectively. 

Epoxide or epoxy resins [14,54,55] contain the epoxide group, also called the epoxy, oxirane, or ethoxyline group, which is a three-membered oxide ring ...
