          Abstract

          Neste trabalho foram obtidos compósitos poliméricos de partículas de madeira de eucalipto e polietileno de baixa densidade reciclado (LDPE reciclado). O polietileno funcionalizado com anidrido maleico (PE-g-MA) foi utilizado como agente compatibilizante para conferir melhor adesão entre a matriz e a fase dispersa. As propriedades mecânicas de tração e flexão foram determinadas de acordo com as normas da American Society for Testing and Materials (ASTM). Os resultados mostraram que o tratamento das partículas de eucalipto com PE-g-MA aumentou as propriedades mecânicas dos compósitos, em relação aos compósitos contendo partículas sem tratamento. Entretanto, as propriedades mecânicas de tração desses compósitos foram reduzidas depois de longo tempo de imersão em água.

          Translated abstract

          In this work polymeric composites were obtained from eucalypt wood particles and recycled low density polyethylene (recycled LDPE). The maleic anhydride functionalized PE (PE-g-MA) was used as compatibiliser agent to provide better adhesion between the matrix and the dispersed phase. The mechanical properties of tensile and flexural were determined in accordance with the American Society for Testing and Materials (ASTM) procedures. The results showed that PE-g-MA as compatibiliser agent increased the mechanical properties, in relation to the composites containing particles without treatment. However, the tensile mechanical properties of these polymeric composites were reduced after long time of immersion in water.
