| Outline of Final Research Achievements |
Effects of addition of cyclic and star-shaped poly(ethylene glycol) (PEG) were investigated for crystallization of linear PEG.
While, by the addition of cyclic and star-shaped PEG, crystal structure and higher-order structure were not effected, crystallization kinetics strongly showed strong dependence on the addition of such topological molecules.
Addition of cyclic molecules suppressed the growth rate of the spherulite, especially for a cyclic PEG with a certain molecular weight. This may be because of increase of entanglement by topological effects.
