A study of the kinetics of swelling in cylindrical polystyrene gels: Mechanical behavior and final properties after swelling

Mechanical properties of cylindrical polystyrene gels were investigated 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 determin...

Description
Summary:Mechanical properties of cylindrical polystyrene gels were investigated 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 gel and the related mesh size. Experimental results were found to be consistent with the theory of Tanaka et al. Elastic moduli were interpreted on the basis of the phantom and affine models.
