Abstract

It has been found that, dependent on the crystallization temperature ( T c ), the disorder (α‘) and order (α) phases of poly( l -lactide) (PLLA) are formed at low ( T c < 100 °C) and high ( T c ≥ 120 °C) temperatures, respectively. In the DSC curves, the sample with α‘ phase demonstrates a peculiar ...
