“…Glycerol was used as a plasticizer for chitosan, as it has good plasticizing power, is nontoxic, and has fairly stable thermal properties. 6 PEgMA was also added as a compatibilizer for interfacial adhesion between LDPE and chitosan. Before mixing, the chitosan powder was dried in an oven for 24 h at 80 8C.…”

“…[3][4][5][6] Blending allows the functional properties of the materials to be enhanced for a broader range of potential applications. Furthermore, as synthetic polymers are commonly available and have a low cost of production, polymer blends are gaining importance because of their favorable balance among their properties, cost, and environmental requirements.…”

Synthetic biopolymer blends are gaining interest in the packaging industry because the incorporation of natural materials imparts biodegradable properties to films. In this study, polyethylene/chitosan (chitosan) films with thicknesses of about 0.3 6 0.01 mm were fabricated via compression molding. The effects of the variation in the length of compounding as a function of the length/diameter (l/d) ratio (15:1, 30:1, 45:1, 60:1, and 75:1) were investigated. The experimental results show that a higher degree of miscibility of the blends was achieved with increasing compounding length; this led to improved mechanical properties in the films, and this was verified by the statistical analysis of data with the analysis of variance procedure. The tensile strength (TS) increased by about 25%, whereas the elongation at break (E break ) increased by twofold. Films fabricated from blends compounded with an l/d ratio of 60:1 had the highest TS and E break values, and the TS was comparable to that of low-density polyethylene films.

“…Se seleccionó el glicerol debido a que su capacidad como plastificante ha sido documentada en la literatura, además de su inocuidad y su buena estabilidad térmica (Ermolovich y Makarevich 2006). Se prepararon películas de PE y quitosano sin compatibilizante y películas en las que se agregó PEgMA como un compatibilizante para la mezcla.…”

Palabras clave: extrusión, propiedades mecánicas, espectroscopía de infrarrojo, degradación en tierra RESUMEN La utilización de polímeros sintéticos como materia prima para empaques desechables genera altos volúmenes de contaminantes persistentes en el ambiente. Una manera de resolver el problema del acumulamiento de plásticos, es la producción de materiales poliméricos biodegradables. En este trabajo se presenta la preparación y pruebas de degradación acelerada de películas preparadas a partir de mezclas de polietileno lineal de baja densidad con quitosano, utilizando anhídrido maléico como compatibilizante. Las películas de polietileno con un 15 % de quitosano perdieron 40 % del valor inicial de resistencia a la tensión después de 360 h de degradación acelerada. En contraste con el 20 % de pérdida que presentó la película de polietileno puro durante el mismo periodo. Las películas con quitosano, además, redujeron 13 % de su peso después de estar bajo tierra de vivero durante 180 días, un valor considerablemente mayor que el 0.05 % que presentó la película de polietileno. La presencia de anhídrido maléico como compatibilizante favoreció un ligero aumento en la degradación de las películas de polietileno con quitosano.Key words: extrusion, mechanical analysis, infrared spectroscopy, degradation in soil ABSTRACTThe use of synthetic polymers as material for the production of disposable packaging, generates high volumes of persistent environmental pollutants.

Functionalization of polyethylene chains by grafting of polar groups onto backbones is the most versatile way for preparing polyethylene based compatibilizers (PECs). In this work, a series of theoretical studies were performed to analyze the structure, adhesion and mixing behaviors of PECs. The effect of grafting different polar groups such as acrylic acid (AA), glycidyl methacrylate (GMA), maleic anhydride (MAH) and itaconic acid (IA) on the structure and cohesive properties of polyethylene chains were studied by Molecular Dynamics simulations. The mixing behavior of grafted polyethylenes with some commodity polymers such as polyetylene teraphthalate (PET), polyamide 6 (Nylon6), polyvinyl acetate (PVA) and polylactide (PLA) as well as with starch (ST) and starch acetate (STac) were investigated quantitatively by determining accurate interaction parameters using the modified Flory-Huggins Theory. We showed that the polar groups are the most reactive sites and they bind the chemically incompatible polymers by enabling the stronger interactions at the interfacial region.
