Melt memory in propene–pentene isotactic copolymers: the case of defects hosted in the crystals

Abstract
Incorporation of pentene in isotactic polypropylene produces a memory of the crystalline state in the melt that persists up to temperatures higher than the melting temperature giving self-nucleation and favoring crystallization of the γ form.
