THERMAL-PROPERTIES AND MORPHOLOGY OF CRYSTAL FORMED ISOTHERMALLY AT MELTING PEAK TEMPERATURE IN NYLON-1010

The thermal properties and morphology of the crystal formed isothermal ly at the melting peak temperature in Nylon 1010 were studied by means of DSC, TEM and ED. The crystal was stable on the time-scale of the D SC experiment and was not transformed from the low melting point cryst al. Its electron diffraction pattern displayed the symmetrical and cle ar electron diffraction spots of a single-crystal and was proved to be the electron diffraction pattern of a single-crystal by the parameter s of the unit cell of Nylon 1010.
