Thermally induced coupling of phase separation and gelation in an aqueous solution of hydroxypropylmethylcellulose (HPMC)

Kita, Rio; Kaku, Takeshi; Ohashi, Hitoshi; Kurosu, Tateki; … - In: Physica A: Statistical Mechanics and its Applications 319 (2003) C, pp. 56-64

Thermally induced coupling of gelation and phase separation in polysaccharide aqueous solutions has a complex feature because of critical and tricritical phenomena, thermally induced hydrophobic interaction, and molecular-weight distribution of the polysaccharide. To elucidate the process, the...
