✦ Synopsis

The relative binding powers of three solid propellant binders [Indian Space Research Organization (ISRO) polyol, polypropylene glycol (PPG) and hydroxy-terminated polybutadiene (HTPB)] have been studied by evaluating solvation numbers using the Passynsky equation based on ultrasonic velocity and density data in a common solvent, viz. tetrahydrofuran. Compatibilities of ISRO polyol-HTPB and PPG-HTPB mixtures have been studied by ultrasonic and viscometric techniques. Rheologlcal parameters have been measured for these solid propellant binders and their mouldability indices have been determined.
