This study investigates the molecular mobility and crystallinity of polytetramethylene ether glycol (PTMEG) in polyurethanes with varying molecular weights, utilizing techniques such as modulated differential scanning calorimetry (MDSC) and dielectric relaxation spectroscopy (DRS). The findings indicate that increasing molecular weight enhances PTMEG crystallization stability, while the glass transition temperature of polyurethanes decreases with higher microphase separation. The research also highlights th
