Studies on the Synthesis of Cellulose Nitrite and Its Application (II) -The regeneration of Cellulose Nitrite to cellulose and the Blending of Cellulose Derivatives with PAN-

셀룰로오스 나이트라이트의 합성과 그의 응용(II) -아질산 셀룰로오스의 셀룰로오스에의 재생 및 셀룰로오스 유도체와 PAN과의 블랜딩-

The effects of the reaction conditions in nitrosation of cellulose and the regeneration conditions of cellulose nitrite to cellulose on the molecular weight of regenerated cellulose, and the blending of cellulose nitrite or cellulose sulfate with PAN were investigated. The results are as follows. The molecular weight of regenerated cellulose is influenced by nitrosation temperature, nitrosation time and the alkalinity of regenerating liquor. X-ray diffractogram shows that the regenerated cellulose has cellulose II structure. Polyacrylonitrile is miscible with cellulose sulfate to a considerable extent, and the film of their blend is so outstanding in anti-static property that it is considered to be able to produce anti-static polyacrylic fiber.
