✦ Synopsis


The effect of liquid-liquid phase separation (LLPS) on the crystallization behavior of poly(ethylene-ran-vinyl acetate) with a vinyl acetate content of 9.5 wt % (EVA-H) in the critical composition of a 35/65 (wt/wt) EVA-H/paraffin wax blend was investigated by small-angle light and X-ray scattering methods and rheometry. This blend exhibited an upper critical solution temperature (UCST) of 98°C, and an LLPS was observed between the UCST and the melting point of 88°C for the EVA-H in the blend. As the duration time in the LLPS region increased before crystallization at 65°C, both the spherulite size and the crystallization rate of the EVA-H increased, but the degree of the lamellar ordering in the spherulite and the degree of crystallinity of the EVA-H in the blend decreased.

Phase separation behaviors of the blends that consist of high-density polyethylene (HDPE) and LP was investigated by means of thermal analysis. The miscibility of the two components was evaluated in terms of the Flory-Huggins interaction parameter, determined from the Hoffman-Weeks plot, gave a valu
