Abstract
Nonisothermal melt crystallisation behaviour and crystallisation kinetics of poly(4,4′-aminocyclohexyl methylene dodecanedicarboxylamide), a novel cycloaliphatic microcrystalline polyamide (named PA PACM12), are investigated by differential scanning calorimetry (DSC). The results show that with decreasing cooling rate, the crystallisation peak becomes narrower and shifts to higher temperature, while the crystallisation enthalpy increases. The Avrami equation, Ozawa model and Mo method are proved to be suitable to describe the whole crystallisation process. Needle-like crystals of PA PACM12 are observed under polarizing optical microscopy (POM), which is in agreement with the characteristics of nucleation type and crystal geometry deduced from the Avrami analysis. 37 Refs.
