Crystallization and the polymorphic transition of poly(vinylidene fluoride) (PVDF) in its miscible blends with poly(butylene succinate) (PBS) from the melt has been investigated. The presence of a miscible PBS component lowers the crystallization temperature and the melting point of the PVDF component in the blends. It becomes more significant above a critical PBS content between 40 and SO wt % where PVDF chains are dispersed in the matrix composed by PBS chains. On the other hand, the beta form of the PVDF component can be induced at low temperatures, which also has a transition at the critical PBS content.
