Synthesis, Structure and Properties of Segmented Polyurethanes

Abstract

The effect of the introduction of mesogenic groups on the properties and structure of segmented polyurethanes was investigated. The objectives were to determine to what extent the phase behavior of such polyurethanes is controlled by the phase behavior of the mesogen and the effect of structural considerations such as hydrogen bonding and asymmetric placement of methyl groups on the phase behavior.
