In the context of polymer crystallization there are several still open and often controversially debated questions. The present volume addresses issues such as

novel general views and concepts which help to advance our understanding of polymer crystallisation
nucleation phenomena
long living melt structures affecting crystallization
confinement effects on crystallization
crystallization in flowing melts
fluid mobility restrictions caused by crystallites
the role of mesophases in the crystal formation
and presents new ideas in a connected and accessible way. The intention is thus not only to provide a summary of the present state-of-the-art to all active works but to provide an entry point to newcomer and graduate students entering the field.
