Shape memory polymers phase change properties

Shape memory polymers with phase change properties... 

These multiblock terpolymers are laboratory products. They were prepared in order to evaluate the influence of the incorporation of a third block into the macromolecule on the copolymer phase structure. An attempt was made to change the morphology (from microphase to nanophase) in the Hytrel -type elastomers thereby, the interphase could be expanded. The elastomers having a nanophase structure are polymers with a better shape memory than those with coarse morphology. By the incorporation of a third block, the properties of multiblock polymers can be modified so that different shape memory effects can be achieved (for shape memory effects, see also Chapter 18).
