Abstract
Novel crystal gels and articles are formed from one or more block copolymers having at least one crystalline midblock and high levels of a plasticizer, said midblock segment having an amount of crystallinity 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 gels.
