NMR study of the homogeneity of distribution of the plasticizer in cellulose nitrates using the pulse gradient of magnetic field

Features of the Structure and Rheology of Nitrocellulose Solutions

“…With weakening of the solution, and with achievement of the critical concentration (about 3 wt%) (specimen H3), there is a change in the dispersed composition of SMPs: T a = 1487, T b = 119. The given conclusion is consistent with the results of work [15] where the concentration dependence of the self-diffusion coefficient (D s ) of macromolecules of CN (N = 11%) in acetone solutions was investigated, and it was shown that in solutions of low-activity CN a linear dependence D s −1 = f(C) is observed only up to a certain concentration of ~3 vol%. At a concentration of >3 vol%, the acetone solutions are concentrated, i.e.…”
