The commercial chip-calorimeter Flash DSC1 is employed to measure their crystallization rates in a broad temperature range. The results show that polyamide crystallizes faster than polyketone at high temperatures, but slower at low temperatures. The faster crystallization is attributed to a lower lateral-surface free energy for crystal nucleation at high temperatures on account of the sheet-like hydrogen bonding in polyamide crystals. The slower crystallization is attributed to the lower molecular mobility for crystal nucleation at low temperatures on account of the higher glass transition temperature of polyamide.
