The incremental plastic deformation of the crystals of block copolymers made of semicrystalline polypropylene endblocks and amorphous ethylene‐ r ‐propylene midblocks occurring during step cycle tensile tests has dramatic effects on the stress‐strain curves. This can be understood from the evolution of the morphology and of the microstructure of the crystalline blocks revealed by X‐ray scattering experiments. © 2010 Wiley Periodicals, Inc.
