STUDIES ON PHYSICAL PROPERTIES Of POLYMER POLY VINYL ALCOHOL PVA In SOLVENTS STRONG HYDROXIDES AND UREA THROUGH ULTRASONIC AND VISCOSITY MEASUREMENT

Abstract

Water soluble Polymers have defied explanation ever since they were recognised over newlinedecades ago and remained in engima for many years to the Physicists. But consistent efforts newlinebased on study of physico-chemical properties have gradually produced many satisfactory newlineexplanations upon which the present day research stands. Researchers have shown newlineconsiderable interest in studying viscosity as well as acoustic parameters of binary liquid newlinemixtures and understanding the molecular interaction involved in them. newline newline
