Abstract
Segmented polyurethanes represented by formula I are block copolymers composed of alternating soft and hard segments. They exhibit properties characteristic of crosslinked elastomers over a wide temperature range but, at higher temperatures, melt and can be processed by techniques used for plastics and fibers(1). This behavior is explained by the fact that the polymers possess a three-dimensional network built up by intermolecular association (crystallization) of the hard segments. It was therefore of interest to study the effect upon polymer properties of changes in hard segment size, distribution, and spacing along the polymer chain.
