Detection and characterization of folded-chain clusters in the structured melt of isotactic polypropylene

IUCrJ, 2021
Despite ceaseless efforts in past decades, the memory effect of semi-crystalline polymers has not been elucidated completely yet. An important reason why is that residual lamellar crystals in the structured melt are difficult to characterize.
