Abstract
Melting behavior of the all-trans planar modification of triblock oligomers H(CH2)(n)(OCH2CH2)(m)O(CH2)(n)H (n = 6, 8, and 10; m = 1-4) was studied by differential scanning calorimetry. The melting point, enthalpy of melting, and entropy of melting were measured and compared with those for n-alkanes that have similar molecular structures. Structural changes in going from t he crystalline phase to the liquid phase were discussed on the basis of the observed thermal behavior.
