Abstract:

The curing characteristics of bisphenol F cyanate resin is analysised by differential scanning calorim- etry analysis.The polymerization reaction process is tracked with infraredspectrum.And the evolution of refraction coefficient is monitored by Abhe Refractometer.The results show that thermal polymerization process of tetramethyl hisphenol F-cyanate ester resin reacts slowly under 160～200℃environment,which is convenient for process opera- tion.The conversion rate of cyano is 36～38%.Prepolymer resin production process can he controlled by refraction coefficient,the appropriate refraction coefficient range of 1.5760 to 1.5820.

Key words:  cyanate ester resin, polymerization reaction, refraction coefficient
