ABSTRACT
In this chapter we consider several important aspects of crystallinity in polymers. It is a remarkably
rich field, and our coverage necessarily limited, but we will raise most of the central issues and
show how many of them have been addressed. In the previous chapter we examined the glass
transition, and introduced it by contrast to crystallization and melting. The first section of Chapter
12, therefore, serves as part of the introduction to the current topic as well. To continue this
introduction, we pose a series of basic questions, and the answers form the outline for the rest of
the chapter.
