摘要

Abstract

Poly(vinylidene fluoride) (PVDF) and poly(butylene succinate-

-24 mol% hexamethylene succinate) (PBHS)

both crystalline polymers

formed melt-miscible crystalline/crystalline polymer blends. Both the characteristic diffraction peaks and nonisothermal melt crystallization peak of each component were found in the blends

indicating that PVDF and PBHS crystallized separately. The crystalline morphology and crystallization kinetics of each component were studied under different crystallization conditions for the PVDF/PBHS blends. Both the spherulitic growth rates and overall isothermal melt crystallization rates of blended PVDF decreased with increasing the PBHS composition and were lower than those of neat PVDF

when the crystallization temperature was above the melting point of PBHS component. The crystallization mechanism of neat and blended PVDF remained unchanged

despite changes of blend composition and crystallization temperature. The crystallization kinetics and crystalline morphology of neat and blended PBHS were further studied

when the crystallization temperature was below the melting point of PBHS component. Relative to neat PBHS

the overall crystallization rates of the blended PBHS first increased and then decreased with increasing the PVDF content in the blends

indicating that the preexisting PVDF crystals may show different effects on the nucleation and crystal growth of PBHS component in the crystalline/crystalline polymer blends.
