The Influence of Programming Conditions on the Triple-Shape Effect of Copolymer Networks with Poly(Omega-pentadecalactone) and Poly(Epsilon-caprolactone) as Switching Segments


A versatile triple-shape material based on the two crystallizable segments poly(ω–pentadecalactone) and poly(ε-caprolactone) was synthesized showing triple-shape capability after application of the typical two-step triple-shape creation procedure at elevated temperatures (TSCP) as well as a one-step programming procedure at high temperature or at room temperature by cold drawing. By applying TSCP and varying the sequence of programming temperatures, the influence of the programming procedure on the triple-shape capability was investigated. The application of such a modified TSCP enabled to a certain extent the control of triple-shape capability by influencing the crystallization behavior of the two switching segments in these copolymer networks.
