Development of High Performance Cyanate Ester Resin Used in Printed Circuit Boards

Some new developments of high performance cyanate ester resin used in printed circuit boards were reviewed,including the effects of catalyst on the cyclotrimeri-zation of cyanate monomers,toughness enhancement and wet/thermal properties of poly(cyanate ester) net andsynthesis of novel cyanate ester resin.The cyclotrimerization of cyanate monomers is catalyst-dependent.Compounding of cyanate ester resin with other polymer or chemical modificaton of cyanate ester monomer resulted in enhancement in toughness of poly(cyanate ester) net.The wet/thermal properties of poly(cyanate ester) net show thermal spikes and reverse thermal effect.New cyanate monomers and poly(cyanate ester) net are being developed for the sake of increasing the thermal and processing property of poly(cyanate ester) net as well as reducing its cost.
