Cyanate ester resins have an attractive range of dielectric properties when considered againsi other candidate materials.
Apart from ihe preparation of polycyanurate dielectric thin films with a uniform and defect-free surface, another objective of this work is io investigate whether and how the cyanate ester monomers undergo plasma polymerization.
Rhone-Poulenc uses two hydroxyl-terminated polybutadiene/acrylonitrile oligomers to toughen its AroCy cyanate ester monomers and prepolymers.
Like the rubber-modified resins, a new group of modified aromatic cyanate ester resins from ICI Fiberite, Tempe, Ariz.

A number of studies of the thermal and thermo-oxidative stability of aryl dicyanate esters have been presented but it is generally accepted that the decomposition mechanism of polycyanurates proceeds in several stages, involving reaction of unconverted cyanate functionality with air born moisture to form an iminocarbonate intermediate before the rapid rearrangement to a carbamate.
Two other new cyanate esters from Bryte Technologies include EX-1505 and EX-1509, both intended for high-temperature applications.
Cyclotrimerization reaction occurs by the reaction of three cyanate groups opening up and forming a symmetrically substituted triazine ring as shown in the literature, resulting in a fully crosslinked polymer.
In each BADCy tri-mer, an s-tri-azine ring was formed from three cyanate group, based on which the content of tri-mers was determined using Fourier transform infrared spectrometer (FTIR).
Cyanate ester resins possess a range of physical and chemical properties that make them amenable to a variety of processing methods (1), (2).
In our earlier work, it was found that the toughness of the epoxy matrices was improved by the incorporation of siloxane, cyanate ester, unsaturated polyester, vinyl ester oligomer, and polysulfone into epoxy resin (17-22).
