The cupric chloride (CC) effect on the viscosity of nitrocellulose (NC, X) 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 from the intrinsic viscosity of the polymer as well as from the kinetics parameters of complex formation and the weight fraction of CC relative to NC, X, determined at the saturation point. The CCP is characteristic of the NC sample and can be related to the cellulose source (wood or cotton) and nitrogen content. The value of X 1/2 can be used as a parameter to elucidate structural differences among NC samples.
