摘要：

Thermograms of methylcellulose solutions have been obtained using samples with different distributions of methyl substituents. It is concluded that hydrophobic interactions between zones of highly substituted units 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 calorimetric experiments.
