A hexagonal crystal with a star-shaped core, a novel crystal morphology never seen before, was found in low molecular weight poly(l-lactide) (LM w-PLLA) modified by a glycine ester based ionic liquid. The increase in polymer chain mobility, caused by ionic liquid dilution and interaction with polymer chains, induced a morphology transformation from hexagon-shaped ring-banded spherulites to a non-banded hexagonal crystal with a star-shaped core.
