摘要：
Novel thermotropic liquid-crystalline cellulose derivatives were synthesized by the addition reaction of hydroxypropylcellulose with isocyanate. The liquid-crystalline cellulose derivatives exhibited columnar mesophases on heating and cooling. The cellulose derivatives formed a water-absorbing resin and their resinous gel films showed water-absorbency and stability with time. The resin plates of the cellulose derivatives were obtained by a hot press process at liquid-crystalline temperatures. They showed a tensile strength that was stronger than that of polypropylene.
