Relations Between Molecular Structure — Morphological Structure and Properties of Polyethylenes
Studies of the crystallization of polymers has matured sufficiently to enable a detailed and specific quantitative analysis to be made of the relation between structure and properties. In this endeavor a careful distinction needs to be made between two different kinds of structures. On one hand there is the influence of molecular or chain structure. Here, the principal variables involved are the chain length for fractions, the polydispersity for whole polymers, and the structural regularity of the chain. In addition, the independent structural variables which define the crystalline state also need to be taken into account and in fact require major attention. There is a synergistic effect between these two different types of variables, the crystallization conditions and the properties of crystalline polymers.
