✦ Synopsis
Ultrasonic velocity, density and absolute viscosities have been measured for solutions of ISRO polyol, a prominent castor oil based solid propellant binder used in the Indian Space Research Organization. The solvation of ISRO polyol has been studied in various solvents. The solvation number is found to be higher in highly hydrogen-bonded solvents. The theoretical and experimental values of the Rao constant of ISRO polyol solution are also found to be identical within experimental error. The compatibility of ISRO polyol with polypropylene glycol, another solid propellant binder, has also been studied by the ultrasonic technique.
