Abstract

New results for isotactic polystyrene/cis‐decalin gels are presented that suggest that a simple fringed micellar model of the gel may not be appropriate. In measuring the room temperature compressive modulus of gels formed at −20°C, it was found that, not only do the gels exhibit significant stress relaxation but also that the isochronal modulus‐concentration diagrams exhibit abrupt changes in modulus (reduced stress) over narrow ranges in concentration rather than the smooth curves (straight lines) typical of swollen rubber and fringed micellar gels.
