This paper studies the preparation of cyanobenzyl azo-dye. The optimal conditions for reaction were determined and properties of the dye were discussed.

The OCN functional group formed triazine network via cyclotrimerzation for DNCY resin system and the addition of catalysts did not change its cure mechanism.

Due to overproduction and China's competitiveness, the company is ethyl cyanoacrylate withdraw from the global market.

Experience had shown that accidents due to cyanoacrylate are handled best by passive, non-surgical first aid.

And the effect of cyano content on the synthetic technique, structure of accumulative state, thermo- oxidative stability and glass transition temperature of PENSU were also discussed.
