a DSC curves of the network samples before (dotted lines) and after (solid lines) isomerization. b DSC curves for the isomerized PEG-2 samples obtained with different UV irradiation times. c Room temperature storage modulus (25 °C) and PEG crystallinities of the isomerized samples. d Gel fraction of the isomerized network samples. Error bars represent standard deviations calculated from three specimens.
