Crystallization kinetics of poly(ethylene naphthalene-2,6-dicarboxylate) as revealed by microhardness

The microhardness technique has been used to follow the crystallization of poly(ethylene naphthalene-2,6-dicarboxylate) (PEN) from the glassy state. The crystallization temperatures investigated ranged from 423 to 448 K. Results are analyzed on the basis of the Avrami equation. Avrami parameters are...
