摘要: Ultrasonic study has become an important research tool in the field of polymers for investigating structure and molecular interactions multi component system. studies were carried out on Polyethylene glycol (PEG 1000) at different concentrations (0-1%) toluene 303K. parameters like adiabatic compressibility, free volume internal pressure calculated. The ultrasonic velocity decreases with increase concentration. effect concentration is analyzed. An attempt been made to blend PEG 1000 PPG 303K various compositions 1:0, 0.8:0.2, 0.6:0.4, 0.5:0.5, 0.4:0.6, 0.2:0.8, 0:1 miscibility nature analyzed through technique. variation composition nonlinear follows S-type pattern, which shows that immiscible. further confirmed other techniques viscosity refractive index
