Paragraph 0033, (2016/11/24)
The invention discloses a double base compound based on phosphonitrile and triazine group. A preparation method of the double base compound comprises the following steps: introducing a triazine group into phosphonitrilic chloride trimer with intrinsically flame retardant property, and substituting six chlorine atoms on the side chains; further introducing a compound containing diamido or dyhydroxyl into the side chains of the triazine group, so as to obtain the double base compound based on phosphonitrile and triazine group. The compound is enriched in elements N and P; because the compound simultaneously contains the phosphonitrile and triazine group, the compound can achieve a flame-retardant effect in the combustion process by virtue of gas phase flame retardance and condensed phase mechanisms and has an excellent char-forming effect, and the generated carbon layer has the effects of insulating heat and inhibiting oxygen and achieves the effects of intumescent flame retardants. In addition, the phosphonitrile and triazine group have a synergistic flame retardant effect in the matrix combustion process. Moreover, the compound is high in heat stability, char-forming rate and processability and can be widely applied to flame-retardant modification of various high polymer materials.

Trypanosoma cruzi and Trypanosoma brucei are parasites that cause Chagas' disease and African sleeping sickness, respectively. Both parasites rely on essential cysteine proteases for survival: cruzain for T. cruzi and TbCatB/rhodesain for T. brucei. A rec
