Abstract Information

In this thesis, oxazoline functional Polystyrene(PS) and MAH grafting Polypropylene(PP) were used as a reactive compatibilizer for PP/GPPS blends and the mechanical property and morphology of the blends were investigated. PP and GPPS showing similar rheological properties were made into simple blends for each composition ratio, hence thermal and mechanical properties were examined. Also the comparison with the dispersive phase of PP and GPPS was executed. PP-g-MAH, similar to OPS in rheological property, was prepared and consequently the melt blends between the 2 phases were prepared. The change in reactivity and morphology with the mixing condition was observed. PP/RPP/OPS/GPPS blends were reactive-extruded prepared and the change in property and morphology with interfacial reaction was examined, followed by comparison with those of simple blends. At 50% PSA content, bi-continuous morphology was formed, showing no improvement in properties, though. RPPB/OPS were reactive-blended using a banbury mixer. And it was concluded from the FT-IR Spectroscopy using heating cell that the reaction between the reactive compatibilizers was done. The result also showed that $2^nd$ reaction occured, where -NH, -COOH groups formed during $1^st$ reaction and unreacted MAH, oxazoline functional group reacted. RPP and OPS was added as a reactive compatibilizer to PPB/PSB during blending using a twin-screw extruder, resulting in the improvement in mechanical properties such as tensile strength and flexural modulus. The results also suggest that the case where reactive compatibilizer was pre-blended and re-mixed showed higher compatibility.
