| 英文摘要 | The liquid-liquid phase separation (llps) is often coupled with other ordering processes such as crystallization. in a polyolefin blend system, overwhelming changes in crystallization kinetics due to concentration fluctuation caused by spontaneous spinodal llps have been observed. consequently, we are proposing a new mechanism of "fluctuation-assisted crystallization". in this process, the usual nucleation barrier could be overcome (or at least partially) by the spontaneous fluctuation growth of llps in the spinodal region. time-resolved polarized optical micrographs for poly-(ethylene-co-hexene) (peh)/poly(ethylene-co-butene) (peb) = 40.60 isothermally crystallized at 117 degrees c for 2 min after llps at 135 degrees c as a function of llps time at 135 degrees c. |
