Reversible Triple-Shape Effect of Polymer Networks Containing Polypentadecalactone- and Poly(ε-caprolactone)-Segments

A reversible triple‐shape effect is achieved for multi‐phase polymer networks based on two different crystallizable segments. The reversibility of the two shape‐changes is based on crystallization induced elongation (CIE) occurring during cooling and melting‐induced contraction (MIC) during heating...

Zusammenfassung:	A reversible triple‐shape effect is achieved for multi‐phase polymer networks based on two different crystallizable segments. The reversibility of the two shape‐changes is based on crystallization induced elongation (CIE) occurring during cooling and melting‐induced contraction (MIC) during heating under constant stress.
