Understanding Thermal Gelation of Methyl-Cellulose Conference Paper uri icon

abstract

  • Thermal gelation of hydrophobically modified cellulose has been studied for several decades. A number of theories have been proposed to describe this complex reversible process which involves competition between gelation and phase separation. By combining different analytical, spectroscopic, imaging and mechanical techniques we are able to offer a unified picture for seemingly diverse observations. We are able to show that differences in the distribution of hydrophobic substitution along the polymer chain are responsible for the differences in behavior observed in different systems.
