Abstract

The influence of atmosphere (inert or oxidizing) and addition of diethyl phthalate as plasticizer on the thermal degradation of ethyl cellulose has been investigated by thermogravimetric, differential thermogravimetric and differential thermal analysis techniques. In the present of an inert atmosphere, the decomposition of ethyl cellulose and plasticized ethyl cellulose occurs in one and two endothermic steps, respectively. In the presence of air, the decomposition of ethyl cellulose with or without plasticization is a very complex process occurring in a number of exothermic stages. In the thermal decomposition, the plasticized ethyl cellulose yields more carbonaceous residue.
