Birefringent Glassy Phase of a Cellulose Microcrystal Suspension Jun Araki,* Masahisa Wada, Shigenori Kuga, and Takeshi Okano Graduate School of Agricultural and Life Sciences, The University of Tokyo, Yayoi 1-1-1, Bunkyo-ku, Tokyo 113-8657, Japan Received August 18, 1999. In Final Form: November 2, 1999 We prepared a stable and highly viscous suspension of cellulose microcrystals by postsulfating the HCl-hydrolyzed cellulose microcrystals. The neutralized suspension was isotropic and showed flow birefringence at low solid content (ca.
