Effects of Attapulgite on the Isothermal Crystallization Behavior of Poly(Butylene Succinate-<i>co</i>-Butylene Adipate)

Abstract

Poly (butylene succinate- co -butylene adipate)/attapulgite nanocomposites were prepared by melt mixing in a HAAKE mixer. The crystallization kinetics of PBSA and its nanocomposites was studied under isothermal conditions by differential scanning calorimetr. The isothermal crystallization kinetics results indicated that attapulgite can induce heterogeneous nucleation, resulting in an improvement on the crystallization temperature and crystallization rate. Both the PBSA and its nanocomposites were correlated to the spherulitic growth form.
