Characterization of K125/diethyl malonate solutions used as simulants for thickened GD / by S.J. Armour. : DR52-5/8-1989E-PDF

"Thickened agents, especially thickened VX, thickened GD and Thickened Lewisite, constitute an appreciable percentage of the USSR chemical arsenal. The report describes the characterization of solutions of diethyl malonate thickened with the acryloid polymer K125-EA, which are used to simulate thickened GD in dissemination trials. The properties measured and required to correlate with and predict dissemination characteristics such as drop size. Density and surface tension were measured as a function of concentration at 25C Viscosity and first normal stress difference in steady shear and storage and loss moduli in dynamic mode were measured as a function of concentration and temperature. Three equations, the power-law, the Carreau and the Allen-Uhlherr have been used to describe the viscosity-shear rate data"--abstract.
