Resumo: | The slow degradation and the high environmental impact caused by inappropriate disposal of polymer products are the main factors prompting scientists to either substitute conventional polymers by biodegradable ones or to enhance biodegradation of short-lived polymer products, particularly those used in packaging. Polymer blends of conventional and biodegradable polymers is one of the alternative solutions found to improve mechanical properties and accelerate polymer degradation after disposal. This work investigates the effect of incorporating different metallic stearates (Zn and Mg) on the rheological, thermal and mechanical characteristics of 75PBAT/25PCL blends processed in an internal laboratory mixer. The results of torque rheometry suggest degradation during processing potentialized with the stearates incorporation, while that of DSC indicated that the crystallinity of the blends increased with the incorporation of additives. TG data showed a reduction in the thermal stability of the systems containing stearates. Incorporation of stearates resulted in strongly thermally degraded systems. Adding up to 0.25% of magnesium stearate to the blend 75PBAT/25PCL leads to a material that combines maintenance or improvement of properties combined with higher decomposition. |

Las mezclas de polímeros de polímeros convencionales y biodegradables son una de las soluciones alternativas encontradas para mejorar las propiedades mecánicas y acelerar la degradación del polímero después de su eliminación. Este trabajo investiga el efecto de la incorporación de diferentes estearatos metálicos (Zn y Mg) sobre las características reológicas, térmicas y mecánicas de mezclas 75PBAT/25PCL procesadas en un mezclador interno de laboratorio. Los resultados de la reometría de torque sugieren una degradación durante el procesamiento potencializada con la incorporación de estearatos, mientras que la de DSC indicó que la cristalinidad de las mezclas aumentó con la incorporación de aditivos. Los datos de TG mostraron una reducción en la estabilidad térmica de los sistemas que contenían estearatos. La incorporación de estearatos dio como resultado sistemas fuertemente degradados térmicamente. Agregar hasta un 0,25 % de estearato de magnesio a la mezcla 75PBAT/25PCL conduce a un material que combina el mantenimiento o la mejora de las propiedades con una mayor descomposición.A lenta degradação e o alto impacto ambiental causado pelo descarte inadequado de produtos poliméricos são os principais fatores que levam os cientistas a substituir os plásticos convencionais por biodegradáveis ou acelerar a biodegradação de produtos poliméricos de rápido descarte, principalmente aqueles usados em embalagens. Blendas poliméricas a partir de polímeros convencionais e biodegradáveis é uma das alternativas encontradas para melhorar as propriedades mecânicas e acelerar a degradação do polímeros após o descarte.
