- Description:
- The goal of this project is to determine whether main chain polyorganosiloxanes exhibt liquid crystalline properties analogues to side chain polysiloxanes and to investigate the relationship between structure and liquid crystallinity. Several main chain polyorganosiloxanes with p-phenylene, p,p'-biphenylene and bisphenolene as mesogenic group and siloxene as flexible spacer were synthesized and characterized. The structures were confirmed by [H, 13C and 29Si NMR. The new polyorganosiloxanes were characterized by DSC, TGA, GPC and Polarizing Optical Microscope. The crystallinity of main chain polyorganosiloxanes is discussed.
