| Resumen en inglés | Cellulose and Lignin are the most abundant polymers in the world. Cellulose fibers occur in different forms and with variable mechanical properties. It can substitute glass fibers, with advantages, as a reinforcing agent for thermoplastics. Lignin is a complex natural polymer containing guaiacyl and syringyl phenolic units, which are responsible for its antioxidant activity, similar to what occurs with the commercial hindered phenols used as primary antioxidants for polymers. We use these two raw materials in combination with polypropylene, high-density polyethylene and polyamide-6 to make biocomposites by extrusion and injection molding. The mechanical properties and stability achieved with these thermoplastics permits to envisage their application by the plastics industry |
