“…En cuanto a la propiedad de flexión de las muestras ensayadas se tiene que la mezcla de 10 % de fibra de plátano y 90 % de polipropileno el material compuesto alcanza su mayor flexibilidad, ya que la fibra es altamente flexible y combina estas propiedades con las de la matriz obteniendo un material que en un gran porcentaje aumenta su flexibilidad. Tanto del material compuesto con fibra de abacá y fibra de plátano podemos observar que las mejores propiedades se obtienen cuando tenemos un 10% de fibra y 90% de matriz (5,16,21).…”

En los residuos sólidos plásticos el polipropileno es uno de los termoplásticos de mayor consumo a nivel urbano y por ende el de mayor generación de residuos. En este sentido, el reciclaje mecánico es la tecnica mas sencilla de aplicación aprovechando de residuos de la misma familia de termoplastico que acondicionado con otras fibras permiten el mejoramiento de sus propiedades, mediante la elaboración de composites con fibras naturales o sinteticas. El presente estudio tiene como objetivo el analisis de las propiedades más importantes de composites hechos de poliproplieno con fibras naturales: de plátano y de abacá; composites de polipropileno con polietilen tereftalato a diferentes concentraciones, con y sin acoplante; y un tratamiento termico para el mejoramiento de la matriz de polipropileno reciclado. Se obtienen probetas mediante extrusión de monohusillo a diferentes perfiles de temperatura y concentraciones de fibra adicionada. Se plantea el tratamiento térmico al polipropileno midiendo el grado de cristalización que se genera. Posterior, se mide la tracción, flexión y calorimetría diferencial de barrido de los composites de buena trabajabilidad usando como acoplante anhidrido terftalico. Los resultados muestran mejoras en las propiedades de tracción y flexión al momento de adición del agente acoplante en ambos composites y con concentraciones bajas de fibra de refuerzo.

“…The compatibility of polymer blends between polyolefin and CNR can be improved by the presence of a compatibilizer or coupling agent from one of the parts of the polymer blends. Mahendra et al [3] reported the improvement of polymer blends between polypropylene (PP) and CNR using PP-g-MA and CNR-g-MA as compatibilizers. The oleic acid-grafted linear lowdensity polyethylene (LLDPE-g-OA) can also be used as compatibilizers to reduce the interfacial tension between the two polymer phases by increasing the interfacial adhesion of the two phases.…”

This study investigates the improvement of the mechanical, thermal, and morphological properties of linear low-density polyethylene (LLDPE)/cyclic natural rubber (CNR) after the addition of organo-precipitated calcium carbonate (O-PCC). The impact on the properties of the LLDPE/CNR/LLDPE-g-OA/O-PCC composites was investigated by a series of empirical experiments. First, the polymer composite was blended in the molten state using an internal mixer with a heating temperature of 160 °C and a rotation speed of 100 rpm. The LLDPE was placed in a chamber of internal mixer until melted, followed by CNR, LLDPE-g-OA, and O-PCC. The polymer composites with an O-PCC concentration of 5% obtained the optimal mechanical properties compared to other variations, with a tensile strength of 17.17 MPa and Young's modulus of 252.68 MPa. The presence of O-PCC resulted in better thermal stability and a change in the melting point temperature of 124 °C. The FTIR spectra of the polymer composite showed the specific characteristics of O-PCC at 872.1 cm–1. The morphology of the polymer composite indicates that the O-PCC is evenly dispersed in the polymer composite.

“…A combination of non reactive and reactive coupling actions of the incompatible polymer phases might subsequently be initiated leading to complex block or graft structures located at the interface [ 18 ]. Improvements of morphology and mechanical properties have been reported by many authors for various materials [ 19 , 20 , 21 ].…”

The influence of reactive processing, non reactive and reactive copolymers on immiscible polypropylene (PP)–polystyrene (PS) blends with varying PS concentrations (10 wt.% and 25 wt.%) was evaluated by mechanical (tensile and tensile impact), rheological (melt flow rate, extensional and dynamic rheology) and morphological (scanning electron microscopy) analysis. As an extended framework of the study, the creation of a link to industrial applicable processing conditions as well as an economically efficient use of compatibilzing agent were considered. For radical processed blends, a high improvement in melt strength was observed while non reactive copolymers exhibited a pronounced increase in toughness and ductility correlated with overall best phase homogeneity. Conversely, the influence of the reactive copolymer was quite different for the varied PS concentrations not allowing the assumption of a specific trend for resulting blend properties, but nevertheless in the case of a lower PS concentration the tensile impact strength exceeded the value of virgin PP. Since PS and PP are widely used, the findings of this work could not only be relevant for the generation of more versatile blends compared to virgin components but also for recycling purposes, allowing the enhancement of specific properties facilitating the production of more valuable secondary materials.
