Abstract

The switching temperature,Tsw, which must be exceeded to initialize a shape-memory effect (SME), and Tσ,max, a temperature related to the recovery stress maximum under constant strain-activation conditions, are adjusted systematically over a wide temperature range for temperature-memory polymers. The polymers are based on crosslinked poly[ethylene-ran-(vinyl acetate)] with crystallizable controlling units and exhibit a broad melting temperature range.
