AbstractIn the investigation reported here, the effective crosslink densities for solid and cellular silicone rubbers were determined from physical tests of solvent‐swollen specimens, and theoretical crosslink densities were calculated from chemical analysis data. A method was developed to accurately measure the compression and the deflection of swollen rubber specimens; and empirical equations were derived which relate compression, deflection, and effective crosslink density of toluene‐swollen specimens of silicone rubber. Flory‐Huggins solvent interaction parameters have been calcu
