アジン化合物を有する新規なポリウレタンの合成および液晶性

抄録

Polyurethane (PU) as an industrial material has been used in paints and adhesives, it is important materials in the modern. In the last few years, the study of the liquid crystal PU having a good liquid crystal groups of orientation for the modification of the PU has been actively conducted. In this study, we were synthesized the polyurethane with an azine unit which exhibit high thermal stability and light stability to the mesogenic groups. The obtained polyurethane was yellow powder of 67.2% yield.
