Trimethylolpropane triacrylate (TMPTA) is a trifunctional acrylate ester monomer derived from trimethylolpropane, used in the manufacture of plastics, adhesives, acrylic glue, anaerobic sealants, and ink. It is useful for its low volatility and fast cure response.
TMP is mainly consumed as a precursor to alkyd resins.Otherwise, acrylated and alkoxylated TMP's are used as multifunctional monomers to produce various coatings, Ethoxylated and propoxylated TMP, derived condensation of from TMP and the epoxides, are used for production of flexible polyurethanes.

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. [ 3 ] [ 4 ] The molecule's acrylate group functionality enables the molecule to do the Michael reaction with amines .
Nonylphenol is also often used an intermediate in the manufacture of the non-ionic surfactants nonylphenol ethoxylates, which are used in detergents, paints, pesticides, personal care products, and plastics. Nonylphenol and nonylphenol ethoxylates are only used as components of household detergents outside of Europe. [2]
In December 2012, the European Chemicals Agency (ECHA) included the substance group “4-(1,1,3,3-tetramethylbutyl)phenol, ethoxylated” – which includes Triton X-100 – in the Candidate List of substances of very high concern [9] of the Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH) Regulation which addresses ...
Pentaerythritol was first reported in 1891 by German chemist Bernhard Tollens and his student P. Wigand. [5] It may be prepared via a base-catalyzed multiple-addition reaction between acetaldehyde and 3 equivalents of formaldehyde to give pentaerythrose (CAS: 3818-32-4), followed by a Cannizzaro reaction with a fourth equivalent of formaldehyde to give the final product plus formate ion.
2-Ethylhexyl acrylate polymerizes easily. The polymerization can be initiated by light, peroxides, heat, or contaminants.It can react violently when combined with strong oxidants and can form explosive mixtures with air at temperatures above 82 °C (180 °F). [2]
