Abstract: | Blends of high-density polyethylene (HDPE) and polyamide 6 (PA6) were produced by ultrasonic extrusion. Ultrasonic irradiation leads to degradation of polymers and in situ compatibilization of blends as confirmed by the variations of linear viscoelastic properties. The results showed that the effect of ultrasonic irradiation on dynamic rheological properties depends on the composition and experimental temperature. At the same time, the relationship between storage modulus and loss modulus quantifies the effect of ultrasonic irradiation on compatibility of HDPE/PA6 blends. Using emulsion model, the interfacial tension between the matrix and the dispersed phase was predicted. The obtained data showed that ultrasonic irradiation can decrease the interfacial tension, and thus enhance the compatibility of HDPE/PA6 blends. | ||||||||||
