Abstract
A study on the swelling properties of SBS and SIS block copolymers was reported. A new relation of the elastic properties of SBS and SIS to the structure of elastomers, the swelling ratio and the nature of selective swelling agents was derived from the statistical theory of viscoelasticity developed earlier for thermoplastic elastomers SBS(SIS). The dependence of viscoelastic free energy of deformation and state equation on the nature of swelling agents and the swelling ratio was also investigated. It shows that the statistical theory of viscoelasticity for SBS(SIS) elastomers has proven to be very useful in characterizing the elastic behavior of swollen multiphase networks of SBS and SIS.
