AB  - Chemical structure and concentrations of coupling agents are the most important in choosing appropriate coupling action between polymer matrix and wood filler in composites. In this study, the efficiency of new amido-acrylic acid (AMACA) coupling agent synthesized for this propose at the Forestry Faculty of the Belgrade University, was compared with two well-known commercial coupling agents, anhydride of maleic acid (in the form of maleated polypropylene MAPP) and silane A-1100 (gamma-aminopropyltriethoxy silane). The polypropylene-wood flour (PP-WFl) composites were produced with 40% of wood particles having a fraction size of 0.3 mm. The melt-blended composites were modified with coupling agents in amounts of 1.7, 4.0 and 6 wt.% (based on wood filler) and successively with 0.05 wt.% (based on PP) of organic peroxide during the mixing step. The composites containing coupling agents showed superior mechanical properties, compared with the untreated ones. The highest extent of improvement of tensile and impact properties was achieved with PP-WFl composites modified by an AMACA coupling agent.

AB  - The ethylene-propylene-dien-monomer (EPDM) is a well known elastomer component for modification of polypropylene (PP) impact properties. The subject of this study is the possibility of improving the properties of polypropylene/wood flour (PP/WFL) composites by using EPDM both as a compatibilizer and coupling agent in quantities of 10, 20 and 30% (relative to PP mass). The tensile modulus of elasticity and tensile strength values are increased in the cases of PP/ WFL composites with 10 and 20% of EPDM content, with respect to PP/ WFL control composites. However, in the case of 30% of EPDM content values of these properties decreased. The IZOD impact resistance values are increased for all test composites, but most of all in the case of composite with 30% of EPDM.
