The growth of polymer crystals is a complex process, especially when the crystals are subjected to various conditions. This chapter, which focuses on the structural evolution of the growth process, begins by discussing some general features of polymer crystallization. (See Chapter 4 for a description of polymer crystal structures.) [Pg.165]

With decreasing temperature, the density oscillation becomes very pronounced and grows into a deeper melt region. At 300 K, for example, we can see at least 5 layers after 1.28 ns. Within the layers, as will be shown later, definite order in chain orientation and chain packing is observed suggesting the growth of polymer crystals. [Pg.63]

Besides the structures already discussed, more complex morphologies may be obtained from the growth of polymer crystals from solutions. The structure that emerges from the crystallization of a polymer is a function of a complex interaction of factors that include the type of solvent, solution temperature, concentration, and polymer molecular weight. Some examples of these structures include spiral growth, dendrites, and hedrites. [Pg.101]

Although the Avrami analysis is fairly successful in explaining the phenomenology of crystallization it does not give any insight into the molecular process involved in the nucleation and growth of polymer crystals. There have been many attempts to develop theories to explain the important aspects of crystallization. Some of the theories are highly... [Pg.280]
