説明
We have succeeded in obtaining the nucleation rate and velocity of the travelling of steps from the nucleation and growth processes of polymer crystallization, utilizing the enhanced growth at re-entrant corners of {110} twinned crystals of polyethylene. The supercooling dependence of nucleation rate is two times as strong as that of growth rate; this fact suggests that the growth is by multi-nucleation (regime II). The velocity of steps is proportional to the concentration of solution and nucleation rate is independent of the concentration over the usual concentration range. These relations suggest that the growth face is saturated with adsorbed polymer molecules and the travelling of steps is controlled by the volume diffusion of polymer in the solution. The method described can be applied to other systems which have the same type of re-entrant corner.
