Abstract

Shape memory effect in pure ultra-high molecular weight polyethylene (UHMWPE) has been studied using dynamic mechanical analysis. Temperature dependencies of properties that define functional characteristics of shape memory polymers (SMP) such as recovery stress, recovery strain and activation temperature of transition were determined for UHMWPE. The recovery stress in UHMWPE deformed by 200% achieved rather high values, up to 7 MPa.
