Epoxy is the family of basic components or cured end products of epoxy resins. Epoxy resins, also known as polyepoxides, are a class of reactive prepolymers and polymers which contain epoxide groups. The epoxide functional group is also collectively called epoxy. [1] The IUPAC name for an epoxide group is an oxirane.
It is primarily used as a curing agent or hardener in epoxy chemistry. This can be on its own or reacted with tall oil fatty acid (TOFA) and its dimer to make an amidoamine. [2] This amidoamine is then used as the curing agent for epoxy resin systems. TEPA is a pentadentate ligand in coordination chemistry.
A compound containing the epoxide functional group can be called an epoxy, epoxide, oxirane, and ethoxyline. Simple epoxides are often referred to as oxides. Thus, the epoxide of ethylene (C 2 H 4) is ethylene oxide (C 2 H 4 O). Many compounds have trivial names; for instance, ethylene oxide is called "oxirane".
Dimethylaminoethanol is used as a curing agent for polyurethanes and epoxy resins. It is a precursor to other chemicals, such as the nitrogen mustard 2-dimethylaminoethyl chloride. [3] The acrylate ester, dimethylaminoethyl acrylate is used as a flocculating agent. [4]
[9] [10] The manufacturing of epoxy resins and vinyl ester resins account for 25–30% of BPA use. [9] [10] The remaining 5% is used as a major component of several high-performance plastics, and as a minor additive in PVC, polyurethane, thermal paper, and several other materials. It is not a plasticizer, [11] although it is often wrongly ...

PETA is part of a family of acrylates used in epoxy resin chemistry and ultraviolet cure of coatings. Similar monomers used are 1,6-hexanediol diacrylate and trimethylol propane triacrylate . It is a derivative of pentaerythritol [ 2 ] One of the key uses of the material is in polymeric synthesis where it can form micelles and block copolymers.
The vast majority of reagents are monosubstituted at the ylide carbon (either R 1 or R 2 as hydrogen). Disubstituted reagents are much rarer but have been described: [1] If the ylide carbon is substituted with an electron-withdrawing group (EWG), the reagent is referred to as a stabilized ylide. These, similarly to sulfoxonium reagents, react ...
