Wood plastics composites (WPC) based on wood filler and thermoplastic matrix have been produced in smaller quantities for several decades in the United States (woodstock, etc.) as well as in the Europe periodically. Extensive research programs in several countries some 15 years ago, gave impact to WPC technology which was developed quickly, and many manufactures have begun to produce WPCs at the beginning of this century. The most WPCs are made with polyethylene or polypropylene matrix and with wood reinforcement in particulate form (e.g. wood flour or fibers). However, mechanical properties of these composites need further improvement, since they are not currently being used in applications which require considerable structural performances. The influences of wood species, geometry and size of wood particles, as well as their ratio to plastic matrix on properties of composites had been investigated extensively. Still, the main problem is incompatibility of matrix vs. wood filler and consequently the luck of good bonding between nonpolar polyolefinic plastic matrix and wood particles, which reduced mechanical properties of produced composites. Hence, the achievement of better bonding by assistance of the new type of coupling agent and /or others additives is the main research objective yet. In this study, amido acrylic acid (AMACA) coupling agent has been applied to wood-polypropylene composites (WPPC). AMACA showed better coupling action than some already know agents. Beside, the procedure of compounding of ingredients to produce granules for the further molding into final WPC product is of great importance.
