Abstract
Mechanical properties of cylindrical polystyrene gels were investigate d both by the kinetics of swelling and uniaxial elastic modulus. These gels were prepared by specific chemical reactions using well-defined difunctional and precursor polymers. From the data of the kinetics of swelling we determined the cooperative diffusion coefficient of the ge l and the related mesh size. Experimental results were found to be con sistent with the theory of Tanaka et al. Elastic moduli were interpret ed on the basis of the phantom and affine models.
