Fecha de publicación: | 2016 | Editor: | Marcel Dekker | Citación: | Polymer - Plastics Technology and Engineering 55: 486-497 (2016) | Resumen: | The purpose of this study is to investigate the effect of treated natural zeolite on the flow behavior, morphology, thermal, and mechanical properties in recycled polyolefin blends. A model polymer blend consisting of 95 wt% polyolefines and 5 wt% polystyrene was studied. Compositions from this recycled blend and dehydrated zeolite in a narrow concentration range (0–5 wt%) were treated with maleic anhydride-grafted polypropylene and initiator dicumyl peroxide. The compositions were characterized by capillary rheometry, wide-angle X-ray scattering, differential scanning calorimetry, scanning electron microscopy, and mechanical tests. The results show a compatibilizing effect of treated zeolite expressed by increase of shear viscosity and improvement of interfacial interactions and impact strength. The results can open wide possibilities for utilization of treated zeolite in recycling of unsorted polymer wastes. | Versión del editor: | http://dx.doi.org/10.1080/03602559.2015.1070865 | URI: | http://hdl.handle.net/10261/134710 | DOI: | 10.1080/03602559.2015.1070865 | Identificadores: | doi: 10.1080/03602559.2015.1070865 issn: 0360-2559 e-issn: 1525-6111 |
