PLASTICIZATION of CELLULOSE NITRATES by MIXING LINEAR AZIDES and NITRAMINES

摘要

The ability of apply a mix of linear nitramines and their derivatives as plasticizer of nitrates of cellulose (NC) is investigated. As plasticizer there has been a mix 2,4-dinitro-2,4,diazopentan, 1-azido-3,5-dinitro3,5-diazogexan and 1,5-diazido-3-nitro-3-azopentan. The scheme of the synthesis of plasticizer is described. There have been obtained the results on the basic physical and chemical properties of plasticizer. The thermal stability of the plasticizer, the rate of NC swelling into the plasticizer, the influence of concentration of the plasticizer to temperatures of relaxation transitions and mechanical properties plasticized NC are studied by means of the methods of the thermal analysis. It is shown, that this plasticizer is capable of plasticizing NC which has the high content of nitrogen. Plasticizer TA, in comparison to with nitroether plasticizers, possesses much higher plasticized effect.
