Abstract : The 'front factor' in the equation of state for fubber elasticity has been measured for a poly (dimethylsiloxane) network swollen in a series of swelling agents. The intrinsic viscosity of a linear poly (dimethylsiloxane) polymer in these swelling agents was also measured. Comparison of the intrinsic viscosity and 'front factor' values indicate that the change in modulus of the network upon swelling arises from the change of preferred conformation of the network chains due to interaction with the swelling agent.
