초록/요약
In-situ copolymer formation and compatibilization of immiscible polymer in blends were discovered to occur during ultrasonic-assisted blending in the melt state. High power ultrasonic wave was imposed on polymer blends. The effect of different blend ratios and sonication time was investigated. The mechanical, thermal, rheological properties and morphology of the blends with and without ultrasonic treatment were studied. The mechanical performance of blends subjected to ultrasonic treatment was significantly enhanced compared to those of identical blends not subjected to ultrasonic treatment. The obtained results indicated ultrasonic treatment induced chemical reactions at the interfaces. Formation of in-situ copolymer was observed as evident by their more stable morphology, enhanced mechanical properties, decrease of gap between two Tg of blends, some peaks that were newly found by using ATR spectra. In-situ copolymer enhances interfacial adhesion between immiscible binary polymer blends and improves the compatibility of binary blends.
