G. Laborie, L. Salmén, C. E. Frazier:] This paper demonstrates the applicability of cooperativity analysis for the glass transition of lignin in wood. In ethylene glycol plasticized wood, the coupling model of relaxation proposed by Ngai allows for quantifying intermolecular coupling associated with the lignin glass transition. The method utilizes Time-Temperature Superposition of viscoelastic properties measured by submersion dynamic mechanical analysis. It is shown that the coupling model by Plazek and Ngai adequately describes segmental relaxation above the lignin glass transition temperature only. No significant difference in intermolecular coupling was found between spruce and yellow-poplar. Copyright © 2004 by Walter de Gruyter GmbH & Co.
