Study on the catalyst system for cyanate ester copper clad laminate

Cyanate ester with excellent dielectric properties, heat resistance, low water absorption and good processability, was widely used in low-loss CCL. This paper studied curing reaction process of the cyanate ester and epoxy by transition metal complex catalyst and assisted catalyst. Then it made research on the CCL dielectric property affected by assisted catalyst. The results showed that assisted catalyst and transition metal complex catalyst have significant synergistic catalytic system. The reaction temperature is significantly reduced. CCL performance, dielectric properties, is remarkably improved.
