Toughening of cyanate ester resins with cyanated polysulfones

Polymer, 1997
Abstract 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 ...

Oligodimethylsiloxane Linked Cyanate Ester Resins

Macromolecules, 2001
A series of dimethylsiloxane linked cyanate ester monomers (NCOC6H4(CH2)3(Si(CH3)2O)nSi(CH2)3C6H4OCN, n = 1, 2, 3) have been synthesized and characterized. Monomer melting points range from 5 to −12 °C, and characterization includes 1H, 13C NMR, and IR spectroscopies and DSC.

Combustibility of cyanate ester resins

Fire and Materials, 2006
Flaming 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 ...

Origin of the Rapid Trimerization of Cyanate Ester in a Benzoxazine/Cyanate Ester Blend

Macromolecules, 2015
Blends 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 ...

Thermal decomposition of cyanate ester resins

Polymer Degradation and Stability, 2002
Abstract 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 ...
