Abstract
The cupric chloride (CC) effect on the viscosity of nitrocellulose (NC) in an acetone solution was studied for various military and commercial type NC samples obtained from different suppliers. The NC samples were produced from wood and cotton cellulose with a nitrogen content between 11.0 and 13.5% and a molecular weight ranging from 20,000 to 800,000. The study was carried out using different NC and CC concentrations and at different shear rates. The addition of CC to the NC solution causes an increase of the viscosity as a function of time due to the complex formation between NC and CC which is accomplished in two stages, each with a specific rate constant. The variation of the viscosity with the shear rate followed a pseudoplastic non-Newtonain behaviour. TRUNCATED
