摘要: 本文通过DSC、WAXD、偏光显微镜、DMA等方法,对LDPE/EVA共混体系进行了研究。结果表明,EVA可使LDPE的熔融峰温提高15℃。并在LDPE结晶过程中起稀释剂作用。LDPE/EVA共混体系为非晶相相容。

Abstract: The crystallization and dynamic mechanical behaviour of LDPE/EVA blends were studied by DSC, WAXD, optical microscopy. Results showed that the melting peak temperature of the LDPE in the LDPE/EVA blends was 15℃ higher than that of the pure LDPE. The EVA acts as a diluent in the crystallization of the LDPE. The LDPE/EVA blend system was compatible in amorphous regions.
