摘要：
Wood polyacrylonitrile composite (WPC) from poplar wood was synthesized. The synthetic process was carried out through benzoyl peroxide (0.05 mol 1(-1)) catalyzed impregnation polymerization of acrylonitrile (6.075 mol 1(-1)) into poplar wood in benzene medium at 70 +/- 1 degreesC. Modification of the properties of WPC over untreated wood was evaluated in terms of compression, impact strength and simultaneous differential thermogravimetry-thermogravimetric-differential thermal analysis (DTG-TG-DTA) in air. Compression, impact strength and resistance of wood against thermo-oxidation were improved with impregnation of polyacrylonitrile. Impregnation of polyacrylonitrile into poplar wood was ascertained through UV-vis spectroscopy and scanning electron microscopy. (C) 2004 Society of Chemical Industry.
