Abstract

Novel crystal gels and articles are formed from one or more of a linear SEBS or radial (SEB).sub.n triblock copolymers having a selected crystalline midblock segment and high levels of a plasticizer, said midblock segment having an amount of crystallinity in the EB copolymer sufficient to achieve improvements in one or more physical properties including improved crack propagation resistance, improved tear resistance, improved resistance to fatigue and resistance to catastrophic failure not obtainable in amorphous SEBS gels.
