中文摘要	the isothermal and non-isothermal crystallization processes of nylon 1212 were investigated by polarized optical microscopy. the crystal growth rates of nylon 1212 measured in isothermal conditions at temperatures ranged from 182 to 132 degreesc are well comparable with those measured by non-isothermal procedures (cooling rates ranged from 0.5 to 11 degreesc/min). the kinetic data were examined with the hoffman-lauritzen nucleation theory on the basis of the obtained values of the thermodynamic parameters of nylon 1212. the classical regime i --> ii and regime ii --> iii transitions occur at the temperatures of 179 and 159 degreesc, respectively. the crystal growth parameters were calculated with (100) plane assumed to be the growth plane. the regime i --> ii --> iii transition is accompanied by a morphological transition from elliptical-shaped structure to banded spherulite and then non-banded spherulite. the development of morphology during isothermal and non-isothermal processes shows a good agreement.
