Cyanate resin is a new high performance thermosetting resin with excellent dielectric performance, hot/wet service temperature, and there was little frequency change range （10-50MHz） in dielectric constant and dielectric loss factor and mechanical performance. It has wide application perspective and will be very competitive in market with other engineering plastics. This paper reviews the main methods of toughening and modified of cyanate resins, including rubbers, thermosetting resins, thermoplastic resin, compounds, and combinations containing unsaturated double bond, organic silicon compounds and nanoparticles. The toughening and modifying mechanism were discussed. The studied status and development trend.of modification of cyanate resins were discussed.
