The 1,4-bis (3,5-dimethyl-4-cyanatobenzyl) benzene (BBZCy) was synthesized successfully by the reaction of 1,4-bis (3,5-dimethyl-4-hydroxybenzyl)benzene(BBZ) with cyanogen chloride in the presence of triethylamine at −5–0°C. Its structure was confirmed by means of FTIR, elemental analysis, MS, and 1H NMR spectra. The monomer of BBZCy was cured by itself or cured with catalysts to form sym-triazine structure. Thermal properties of cured BBZCy were studied using DSC, DMA, TMA, and TGA. Compared with the commercial bisphenol A dicyanate resin (BADCy), the cured BBZCy resin exhibited a lower dielectric constant (2.66 at 1 GHz), a lower dissipation factor (0.0054 at 1 GHz), lower water absorption (0.8% at 100 h), less thermal stability, and lower glass transition temperature. © 2011 Wiley Periodicals, Inc.
