When semi-crystalline polymers are crystallized under shear or elongational flow, socalled shish-kebab structures are formed. This structure is of particular interest because it is believed that it is a structural feature of ultra-high modulus and ultra-high strength fibers. A study of the formation process of shish-kebab structures in isotactic polystyrene shows that they emerge from string-like precursors, the formation of which is possible because of the high melting temperature of the crystals under shear flow.
