REDIGHIERI, Karla I.  e  COSTA, Dilma A.. Composites of recycled polyethylene and reforestation wood particles treated with modified polyethylene. Polímeros [online]. 2008, vol.18, n.1, pp.5-11. ISSN 1678-5169.  https://doi.org/10.1590/S0104-14282008000100006.

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.

Palavras-chave : Composites; compatibiliser agent; mechanical properties.
