Exothermic processes in mixtures of polymer with 50 wt.% Al after plastic deformation at high pressure

Abstract

We have investigated thermal degradation of cellulose, polypropylene, low-density polyethylene, high-density polyethylene, polycarbonate, polyimide, polyvynilalkohol, polyvynilchloride, polystyrene, and polyphenilenoxide using DSC method and thermogravimetric and also thermal processes in mixtures polymer - 50% aluminum after plastic deformation at pressure 1 GPa. Thermal degradation of polymers accompany by exothermal effects; the enthalpy varies from 3 to 19,5 kJ·g -1 . Enthalpy of aluminum oxidation varies from 3 to 16,7 kJ·g -1 .
