Fire‐resistant cyanate ester–epoxy blends

Fire and Materials, 2003
AbstractThe cure chemistry, thermal stability and fire behaviour of a series of fire‐resistant cyanate ester–epoxy blends were examined. The dicyanate and diepoxide of 1, 1‐dichloro‐2, 2‐bis(4‐hydroxyphenyl)ethylene (bisphenol‐C, BPC) were combined in various molar ratios and the reaction chemistry was monitored using Fourier transform infrared ...

Polyfunctional cyanate esters for preparing composite materials

Russian Journal of Applied Chemistry, 2014
Reaction of a polyfunctional cyanate ester with an epoxy oligomer was studied. A procedure for preparing a binder for composite materials by the solvent-free prepreg technology was developed, studied, and optimized. Curing of this binder occurs without release of by-products and leads to the formation of a heat-resistant polymeric matrix.

Dielectric properties and mechanism of composites by superposing expanded graphite/cyanate ester layer with carbon nanotube/cyanate ester layer

Composites Science and Technology, 2014
Abstract Electronic conductor/polymer composites with high dielectric constant have great potential in many cutting-edge fields, but they usually show high dielectric loss. Here, new composites (MWCNT/CE–5.0EG/CE) were prepared by superposing a multi-wall carbon nanotube (MWCNT)/cyanate ester (CE) composite layer with another expanded graphite (EG ...

Novel modification of cyanate ester by epoxidized polysiloxane

Journal of Applied Polymer Science, 2007
AbstractA novel modification of cyanate ester (CE) resin by epoxidized polysiloxane (E‐Si) has been developed, and the modified system is coded as CE/E‐Si. E‐Si was prepared by the reactions among octamethylcyclotetrasiloxane, hexamethyldisiloxane, (3‐aminopropyl)‐methyldiethoxysilane, and diglycidyl ether of bisphenol‐A resin.

Cure monitoring of catalysed cyanate ester resins

Polymer International, 2000
The cure behaviour of two bisphenol A-based cyanate ester resins, AroCy B10 and B30, catalysed by copper acetylacetonate and nonylphenol was studied. For this purpose, differential scanning calorimetric (DSC) and rheological measurements were carried out at temperatures between 130 and 170 °C.

Cyanate Esters - High Performance Resins

1986
Cyanate esters of poly phenolic compounds were first prepared by E.Grigat in the early 1960’s. The crystalline, highly pure monomers were made by reacting phenols with cyanogen halide in the presence of a base. Cyanate esters, like isocyanates, undergo a number of interesting reactions which lead to thermoset polymers.
