Synthesis and application of fluorinated epoxy compounds
Emerging Materials Research, 2015A novel fluorinated epoxy compound (FO) is synthesised via one-step method using potassium and sodium aqueous solutions as catalysts. The structure is characterised by Fourier transform infrared spectroscopy and electro spray ionisation-mass spectrometry. The effects of the reaction time and catalysts are measured.

Aliphatic-Cycloaliphatic Epoxy Compounds and Polymers
2007Aliphatic-cycloaliphatic epoxy compounds (ACECs) contain different epoxy groups in the molecule: glycidyl, i.e. 2,3-epoxypropyl groups, and cycloaliphatic, i.e. 1,2-epoxycyclopen-tane or 1,2-epoxycyclohexane rings. The epoxidation of double bonds in cycloolefins was carried out using aqueous peracetic acid (PAA).

Polymerization compounding: Epoxy‐montmorillonite nanocomposites
Polymer Engineering & Science, 2002AbstractA strategy to design intercalated montmorillonite nanocomposites has been explored. A commercial organoclay, 1.34 TCN (Nanocor Inc.), with bis(2‐hydroxylethy1) methy1 tallow ammonium, was modified by tolylene 2,4‐diisocyanate (TDI) and bisphenol A (BA).

Alkylation of pyridinecarbaldehyde oximes with epoxy compounds
Russian Journal of Organic Chemistry, 2007O-and N-Alkylation products were obtained by reactions of pyridine-2-,-3-, and-4-carbaldehyde oximes with enantiomerically pure and racemic epoxy compounds (1,2-epoxypropane, 1-phenyl-1,2-epoxyethane, 1-chloro-2,3-epoxypropane, and 1-bromo-2,3-epoxypropane) in the presence of bases and under conditions of phase-transfer catalysis. A series of new amino

Occupational dermatoses from epoxy resin compounds
Contact Dermatitis, 1990This study comprises 40 patients with skin disorders from current or previous occupational exposure to epoxy resin compounds (ERC) during 1984–1988. ERCs were the 3rd most common cause(32 of 264 cases; 12.1%) of currently relevant allergic contact dermatitis: 23 cases from epoxy resins based on the diglycidyl ether of bisphenol A (DGEBA‐ERs).

A Coarse-Grained Model for Epoxy Molding Compound
The Journal of Physical Chemistry B, 2014We present a coarse-grained model for molecular dynamics simulations of an epoxy system composed of epoxy phenol novolac as epoxy monomer and bisphenol-A as the cross-linking agent. The epoxy and hardener molecules are represented as short chains of connected beads, and cross-linking is accomplished by introducing bonds between reactive beads.
