Thermophysical analysis of plasticized epoxy compounds
Journal of Engineering Physics, 1973A study has been made concerning the effect of dibutylphthalate and thiocol plasticizers in various concentrations on the structure as well as the thermophysical and the mechanical properties of grade ED-5 epoxy resin. It is shown that the entire complex of analyzed thermophysical properties changes appreciably, depending on the kind and on the ...

Ablation resistance of certain epoxy compounds
Polymer Mechanics, 1972The rate of ablation in oxidative and inert media at flow velocities up to 200 m/sec has been investigated for certain epoxy compounds containing powdered copper and zinc dust. The causes of ablative destruction and the factors tending to improve the ablation resistance are examined.

Reaction of epoxy compounds with salts of thioacids
Bulletin of the Academy of Sciences of the USSR Division of Chemical Science, 19711. When the alkali metal salts or the ammonium salts of O,O-dialkyl thiophosphates or O,O-dialkyl dithiophosphates are reacted with epoxy compounds the latter undergo thioepoxidation.

An investigation of the polymerization of pyridine with epoxy compounds
Polymer, 1986Abstract The chemical reaction between pyridine and epoxy compounds has been investigated. This reaction disrupts the aromatic nature of the heterocyclic ring of pyridine, resulting in the formation of a polymeric material that contains cyclic amide structures. The polymer formed is not due to the homopolymerization of the epoxy groups.

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.

Cyclisation Reactions with Participation of Epoxy-compounds
Russian Chemical Reviews, 1970The review deals with reactions of epoxy-compounds in which they are involved in the formation of cyclic structures. Intramolecular rearrangements with participation of epoxy-compounds can lead to alicyclic and heterocyclic compounds. Intermolecular condensations of epoxy-compounds with various reagents give rise to heterocyclic structures.

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

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).
