Double Melting Behavior of Poly(Ether-Ether-Ketone).

Abstract

The melting behavior of semicrystalline poly(ether-ether-ketone) (PEEK) has been studied using differential scanning calorimetry (DSC). When cold-crystallized from the amorphous glassy state at high supercooling or when melt-crystallized at low supercooling, PEEK usually shows two melting peaks. This double melting behavior can be explained by the sum of four contributions: melting of most original crystals, their recrystallization, remelting of recrystallized PEEK and finally the melting of residual crystalline regions.
