International Journal of Radiation Applications and Instrumentation. Part 33 (3) : 205-210. ScholarBank@NUS Repository. | 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. © 1989. | Source Title: | International Journal of Radiation Applications and Instrumentation.
