Özet

Several hard and soft wood species (e.g., poplar, beech, alder, pine, fir and spruce), originated from Turkey, were prepared to wood plastic composites (WPC) with styrene (St) and a mixture of styrene and methylmethacrylate (St-MMA) monomers by using capillary uptake method. The average water uptake of the monomers-treated wood specimens was approximately between 43 to 64% due to water soaking for 72 h. The average water repellent effectiveness (WRE) of WPC was 54% and 55% for St and St-MMA, respectively. As far as water uptake is concerned, poplar gave the highest WRE values, whereas beech had the lowest one.
