Fig. 1. DMTA of TBPE samples (heated from −60 to 160 °C, at 5 °C min−1, 1 Hz frequency, 1% amplitude strain). (A) DMTA of TBPE-7 showing two glass transitions and a theoretical operating temperature window from −41 to +136 °C; (B) storage moduli for TBPE-6 to -9 showing increasing plateau moduli with hard domain content (fhard 0.12 to 0.29).
