Structure development in cyanate ester polymerization [PDF]
Polymer International, 1997 We present results on the product distribution obtained from the polymerization of the dicyanate monomer of bisphenol A carried out under different reaction conditions. Small quantities of side-products were observed using both size exclusion chromatography and high-pressure liquid chromatography for samples polymerized under an inert atmosphere ...

Hydrolysis and blistering of cyanate ester networks [PDF]
Journal of Applied Polymer Science, 1997 The hydrolysis of a cyanate ester network made from the monomer 2,2*- bis(4-cyanatophenyl)isopropylidene (bisphenol A dicyanate homopolymer) was stud- ied. Hydrolysis reactions were performed isothermally at temperatures from 150 to 1807C under conditions of excess water. The kinetics of the reaction were characterized by the decrease in Tg as measured

Origin of the Rapid Trimerization of Cyanate Ester in a Benzoxazine/Cyanate Ester Blend
Macromolecules, 2015Blends of cyanate ester and benzoxazine have been independently studied by several researchers, and different reaction mechanisms were reported. Recently, we unexpectedly observe that gelation occurred in a 50 wt % methyl ethyl ketone solution of P-oda/BACY (1/1 mol/mol) blend after 24 h at 30 °C, in which P-oda is a 4,4′-oxyaniline/phenol-based ...

Toughening of cyanate ester resins with cyanated polysulfones
Polymer, 1997Abstract Bisphenol-A dicyanate (BADCy) resin was toughened by incorporating polysulfone (PSF) and cyanated polysulfone (CN-PSF). CN-PSF was synthesized by the bromination of PSF and cyanation. The effects of PSF content and interfacial adhesion between the matrix and the domain were investigated on the fracture toughness and morphology of BADCy/PSF ...

Combustibility of cyanate ester resins
Fire and Materials, 2006Flaming and non-flaming combustion studies were conducted on a series of polycyanurates to examine the effect of chemical composition and physical properties on the fire behavior of these crosslinked, char forming, thermoset polymers. Heats of complete combustion of the polymer and fuel gases were determined by oxygen bomb calorimetry and pyrolysis ...

Thermal decomposition of cyanate ester resins
Polymer Degradation and Stability, 2002Abstract Polycyanurate networks were prepared by thermal polymerization of cyanate ester monomers containing two or more cyanate ester (–O–C≡N) functional groups. The thermal decomposition chemistry of nine different polycyanurates was studied by thermogravimetry, infrared analysis of solid films, and analysis of the gases evolved during pyrolysis ...
