摘要

Abstract

The non-isothermal crystallization kinetics of reactive microgel/nylon 6 blends was investigated by differential scanning calorimetry (DSC). The Mo equation was employed to analyze the non-isothermal crystallization data. The crystallization activation energies were also evaluated by the Kissinger method. The results show that the crystallization onset temperature (T

onset

) and crystallization peak temperature (T

) decrease with the increase of the content of reactive microgel

while ΔT (T

onset

-T

)

the crystallization half-time (t

1/2

) and the crystallization enthalpy (ΔH

) increase. The required cooling rates of blends are higher than that of neat nylon 6 in order to achieve the same relative crystallinity in a unit of time. The crystallization activation energies of the reactive microgel/nylon 6 blends are greater than those of the neat nylon 6. When the content of reactive microgel is 30%

the relative crystallinity (X

) reaches the maximum.
