Temperature-Memory Polymer Networks with Crystallizable Controlling Units

The switching temperature, T-sw, which must be exceeded to initialize a shape-memory effect (SME), and T-sigma,T-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.
