At a lower degree of undercooling (crystallization temperature of
25 °C), the melting curves of the MP blends showed a bending at
lower temperatures in the beginning of the isothermal period
(Fig. 9). This bending can be associated with the melting of the
low-melting TAGs of PO present in the α polymorph (Fredrick et al.,
2008). The α crystallization at a crystallization temperature of 25 °C
was much more limited compared to a temperature of 15 °C (Fig. 6)
due to the lower degree of undercooling. The α bending was absent
at a crystallization temperature of 28 °C (data not shown). During
further isothermal crystallization, the peak of the MP/higher-melting
TAGs of PO steadily growed
