제목 Influence of Ionic association on the Non-isothermal crystallization kinetic of the lightly Sodium sulfonated Poly(butylene succinate) (PBS) ionomers
초록 Poly (butylene succinate) (PBS) ionized by introducing sulfonated dimethyl fumarate (SDMF), which possesses sodium solfonated ionic group, and the relationship between the ionic group and the non-isothermal crystallization behavior was appraised. The effect of sodium ion group on the molecular structure in PBS backbone was investigated by solid-state 23Na-NMR analysis and confirmed that the creation of aggregated sodium ion (multiplets) predominated with the ionic group concentration, which generate not only the remarkable heterogeneity but also the large degree of clustering in the PBS molecular chains. The nucleation activity exhibited various values depending on the added ionic group concentration.
