Methylcellulose is a natural polymer which gels on heating. This gelation is thermoreversible and attributed to hydrophobic interactions. Its mechanism is not well understood but the presence of hydrophobic zones is needed to initiate the physical crosslinking. Dynamic mechanical experiments performed in a large frequency range are presented and allow discussions for improving our understanding of...
Methylcelluloses are widely used for industrial purposes due to their peculiar properties. These are the consequence of associative behaviour due to hydrophobic interactions involving highly substituted units. The properties of commercial samples with heterogeneous distribution of the substituents and laboratory-made samples, with a more homogeneous distribution, are compared to allow a better understanding...
