N2 - The lyotropic liquid-crystalline behavior of trimethylsilyl hydroxypropylcellulose (TMS-HPC) is reported in this paper. The introduction of the trimethylsilyl (TMS) group in the parent HPC increases the solubility in organic solvents, and the lyotropic mesophase can be formed in concentrated acetone solution. The critical concentration (C*) in acetone is approximately 36%. The liquid crystalline nature of TMS-HPC/acetone solution was confirmed by PLM, and the mechanism of liquid crystallization was studied by FTIR and WAXD methods.
