“…[4][5][6] Acrylic-based polymers and MMA treatment generally enhance the physical and mechanical properties of wood, especially for low-density woods such as poplar. [6][7][8][9][10][11][12][13][14][15] The MMA treatment of yellow poplar (Loriodendron tulipifera L.) reduced moisture adsorption and swelling rates by 60-90%.…”

The surface properties of fast-growing poplar clones and their methyl methacrylate (MMA)-hardened wood related to potential end uses were investigated. Samples from 24 trees of six hybrid poplar clones in one plantation in Quebec were hardened with MMA. The effects of MMA hardening on the density and surface properties were studied. Scanning electron microscopy and Fourier transform infrared analysis showed that filling the voids in the wood structure was the main hardening mechanism. The incorporation of the polymer increased the density of all of the poplar clones by 120-160%. The Janka hardness was found to be 2.5-4 times higher in the treated poplar wood than in the untreated poplar wood. The treated wood also exhibited superior abrasion resistance compared to the controls. The results indicate that hardening with MMA improved the surface properties and that the MMA-hardened wood was comparable to natural hardwoods.

“…It is well known that γ‐irradiation has been extensively investigated in grafting polymer chains onto polymeric backbones,31, 32 modifying polymer blends,33 preparing polymer composites,34 and hydrogels 35, 36. These techniques have been applied extensively in industry as they are environmentally friendly and runs without any metal contamination or additional initiators at room temperature.…”

In this work, atom transfer radical polymerization (ATRP) of methyl methacrylate (MMA) was successfully carried out at room temperature (25 °C) under 60Co γ‐irradiation environment. The polymerization proceeded smoothly with high conversion (>90%) within 7 h. The polymerizations kept the features of controlled radical polymerization: first‐order kinetics, well‐predetermined number‐average molecular weights (Mn,GPC), and narrow molecular weight distributions (Mw/Mn < 1.25). 1H NMR spectroscope and matrix‐assisted laser desorption/ionization time‐of‐flight mass spectrometry confirmed that poly(methyl methacrylate) (PMMA) chain was end‐capped by the initiator moieties. The Cu(II) concentration could reduce to 20 ppm level while keeping good control over molecular weights. This is the first successful example for the ATRP of MMA under 60Co γ‐irradiation at room temperature. © 2011 Wiley Periodicals, Inc. J Polym Sci Part A: Polym Chem, 2011
