the cupric chloride (cc) effect on the viscosity of nitrocellulose (nc) in acetone solution was studied for various wood and cotton nitrocellulose samples with different nitrogen content and molecular weights. the addition of cc to nc solution causes an increase of the viscosity as a function of time due to complex formation between nc and cc which is accomplished in two stages each with a specific rate constant. an empirical factor, the 'cupric chloride parameter' (ccp), is computed which is characteristic of the nc sample and can be related to the cellulose source (wood or cotton) and nitrogen content.
