Modification of Bisphenol A Dicyanate Ester by Carboxyl-Terminated Liquid Butadiene-Acrylonitrile and Its Composites.

The article evaluates the introduction of carboxyl-terminated liquid butadiene-acrylonitrile (CTBN) to improve the toughness of bisphenol. The addition of CTBN in the system had a great influence on the gelation time of the systems at lower temperatures. Moreover, mechanical properties of Dicyanate resin can be largely improved by the addition of CTBN with little loss of thermal properties and dielectric properties.
