| 中文摘要 | isothermal crystallization kinetics in the melting of poly(ethylene oxide) (peo) were investigated as a function of the shear rate and crystallization temperature by optical microscopy. the radial growth rates of the spherulites are described by a kinetics equation including shearing and relaxation combined effects and the free energy for the formation of a secondary crystal nucleus. the free-energy difference between the liquid and crystalline phases increased slightly with rising shearing rates. the experimental findings showed that the influence of the relaxation of peo, which is related to the shear-induced orientation and stretch in a peo melt, on the rate of crystallization predominated over the influence of the shearing. this indicated that the relaxation of peo should be more important so that the growth rates increase with shearing, but it was nearly independent of the shear rate within the measured experimental range. |
