Abstract
Thermograms of methylcellulose solutions have been obtained using samp les with different distributions of methyl substituents. It is conclud ed that hydrophobic interactions between zones of highly substituted u nits are at the origin of the gelation. A minimal value of the degree of substitution (equal to 1.2) is demonstrated to be necessary for the gelation to be observed either from enthalpy calculations or by calor imetric experiments.
