The condition for formation of tetramer of cyanogen chloride, kinds of solvent and catalyst used, the concentration of cyanogen chloride in the solution, the effect of moisture, the temperature and time required for polymerization and the reaction mechanism by use of bromine as a tracer were investigated. The results are summerized as follows: 1. The hydrogen chloride is an essential catalyst; 2. hydrogen chloride additive product of cyanogen chloride is related to the polymerization process; 3. this additive compound liberates hydrogen chloride in the formation of triazine nucleus, and 4. the tetramer (T.C.C.) is not obtainable from cyanulic chloride. These results indicated the reaction mechanism that the additive compound of cyanogen chloride with hydrogen chloride was formed at first, from which the dimer was formed, the reaction of the dimer with the additive compound gave a trimer and that the reaction of the two dimers gave a tetramer.
