Abstract:

The effect of magnetic field on recrystallization of polyoxymethylene(POM) from the melt was stu-died by means of scanning electronic microscope(SEM), differential scanning calorimetry(DCS), X-ray diffraction(XRD) and Fourier-transform infrared(FTIR) spectrometry, and the mechanism of magnetic process to POM was investigated. The results show that lamellae thickness, lamellae interval, and the melting point of POM are increased under 12 T high magnetic field. The molecule chain is affected and lamella is crystaled along magnetic field.
