STABILITY OF THE SUPERMOLECULAR STRUCTURE OF GELS OF LITHIUM TETRAALKYLBORATES BY THE ACOUSTO-OPTICAL METHOD
Z. T. Dmitrieva, N. D. Khat'kov, and N. A. Khomchenko UDC 541.49:547.253 The destructive action of ultrasonic radiation on hydrocarbon gels of [B(OR)4]Li complexes has been investigated. It has been established that the destruction and relaxation of the macrostructure of these gels under the action of acoustic radiation depend on the time of this action and the voltage applied to them. The kinetic dependences of the change in the refractive index and in the dynamic viscosity of the gels being investigated were determined as the response of structurized solutions of the indicated complexes to ultrasound action. Mathematical models are proposed for quantitative estimation of the kinetic parameters of the destruction<196>relaxation of the supermolecular structure of the gels of the complexes being considered.
