A DSC thermograms of P(3HB) and P(3H2MB) during the first heating scan from 50 to 220 °C and the second heating scan from ‒50 to 220 °C after rapid quenching from the melt in the first heating scan. B DSC thermograms of polymers during successive heating and cooling scans recorded at 20 °C/min. The crystallization rates of these polymers were evaluated by the index ΔT (=Tm‒Tc). C Half-crystallization times (t1/2) of P(3H2MB), P(3HB), PLLA, and iPP at various isothermal crystallization temperatures (Tiso). D Polarized optical microscope images of P(3HB) and P(3H2MB) at different Tiso values.
