|Abstract:||The dynamic storage modulus E′ of rubberwood (Hevea Braziliensis) increased after the in situ polymerization of methylmethacrylate in the wood cellular structure. A significant linear relationship existed between the percentage increase in E′ and polymer loading. A thermal scan of tan δ values between -120° and 200°C revealed that the damping pattern of rubberwood was affected to different extents by three different polymeric systems. Poly(styrene-co-acrylonitrile) caused the greatest change in the damping pattern, followed by polymethylmethacrylate-dioxane, and polymethylmethacrylate. This observed trend was attributed to the relative extent of monomer penetration and interaction with the wood cell-wall components.|
