Abstract
PURPOSE: To produce a high-molecular substance having a polyurethane bond, which can be molded and processed into film, fiber, etc. and yet shows a liquid crystal behavior, by the polymerization reaction of o-toluidine isocyanate and an α,ω-alkanediol.
CONSTITUTION: o-Toluidine isocyanate is dissolved in a solvent, such as purified anisole. To this solution is added an α,ω-alkanediol of formula I (n≥5), e.g., 1,6-hexanediol or 1,12-dodecanediol, and the mixture is reacted with heating. The resultant is then cooled, and a diluting solvent, such as acetone, is added so as to separate the reaction product in the form of a solid, which is collected by separation from the liquid phase. Subsequently, the product is further purified by reprecipitation or other means to give the object high-molecular liquid crystals with their main chain structure composed of repeating units of formula II. The resulting high- molecular liquid crystals can readily be molded and processed into film, fiber, etc. and have the possibility for extensive application in the field of electronics, etc.
