Descrição: Copolymers of glycolide and ε-caprolactone were studied using differential scanning calorimetry and solid-state NMR. The variation of the T 1 relaxation time with temperature reflects local disorder and can be quantified in terms of the distribution of correlation times predicted by the Davidson–Cole model. T 1 relaxation is dominated by trans–gauche isomerisation, with an activation energy of 34–35 kJ mol −1.
