Crystallization kinetics of poly(ethylene terephthalate)/ poly(ethylene 2,6-naphthalate)/DBS blends

摘要

The crystallization kinetics of poly(ethylene terephthalate)/poly(ethylene 2,6-naphthalate)/DBS blends were investigated by DSC. The results showed that a little nucleating agent could increase the crystallization rate obviously. When the content of DBS increase (more than 3%), the crystallization rate decrease gradually. The change of apparent activative energy of the blends was similar to n from Avrami equation. The nucleating affected nucleation rate and did not affected equilibrium melting points.
