Double-melting behavior of poly(ether ether ketone)

摘要: 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 low supercooling, PEEK usually shows two peaks. This double can be explained by sum four contributions: most original crystals, their recrystallization, remelting recrystallized and finally residual crystalline regions.
