　 (Analysis of polyethylene spherulite formation processes)

Time variation in the Hv two-dimensional scattering pattern when the sample temperature jumps from the dissolved state (left alone for 10 minutes or longer at 160°C) to 120°C

→ Time variation in scattering intensity angle dependence data

→ Time variation of the spherulite radius By linear approximation of the data for the spherulite radius and time, the spherulite growth rate is calculated from the gradient as 0.8 μm/sec.
