| Abstract: | Three polyurethanes are prepared by the reaction of mesogenic dids with 2, 4toluenediisocyanate. The relation between molecular construction and thermal properties, the treatment conditions of sample and thermal properties were studied by DSC. It is found that the melt point of the polyurethane decreased with the increase of flexible chain length, the melt point and the crystallinity increased with the increase of annealing temperature and annealing time. |
