摘要：

The crystallization dynamics of Nylon 66/Nylon 6 blends, the crystalline/crystalline polymer blends, was analyzed by DSC under isothermal conditions. The crystal growth rate (G) and the nucleation rate (N) depended on both the degree of supercooling (Delta T) and the blend mass fraction (phi). The Delta T /T-m(0) values obtained at the fixed G, which corresponded to the chemical potential difference of molecules between liquid and crystal states, and the surface free energy parameters evaluated from G and N depended on phi for blends. The results suggested that Nylon 66/Nylon 6 blends with phi(N66)> 0.80 or phi(N66)> 0.15 are miscible.
