The strain recovery of three syndiotactic polypropylenes (s-PPs) differing in the percentage of [rrrr] pentad is investigated. A suitable method based on loading-unloading tests at constant displacement rate in tensile loading conditions is adopted to measure the residual and recovered strain components of the applied strain. The method allows to obtain a large amount of data from few tests and to explore a wide strain range. The dependence of the material's strain recovery on the applied strain is analyzed in relation to s-PP strain-induced microstructural changes and crystalline form transitions, which are reported in literature.
