为了弄清楚不同化学试剂处理引起木材内部分子构造的变化及其分子的运动状态，该研究针对杉木试材，采用动态粘弹性分析仪，测定了含水率在纤维饱和点状态下脱木索处理木材、DMSO处理木材和非晶化处理木材以及素材，在-100—10℃、0.5-10Hz的动态粘弹性。

In order to provide an overall understanding on the basic theory and previous researches of wood chemical rheology, the author discusses some respects on the basis of the common knowledge of deformation and flow, which served as the foundation of wood chemical rheology. These respects include the results by Stein and Tobolsky, such as the correlation between the change of polymolecular structure and stress relaxation, the classification of physical rheology and chemical rheology, the difference between the research on wood chemical rheology and other methods, as well as a kind of non\|continuous method to measure stress relaxation proposed by Tobolsky \%et al.

Aging mechanism of wood-plastic composite was: light and heat break down the long molecular chains of wood flour and plastic; the free radicals reacted with the oxygen, which generated carbonyl groups, hydroperoxides and so on; the free radicals also had cross linking reaction, which generated alkoxy; Water destroyed the interface of wood flour and plastic, hydrolyzed ester additives, extracted the small molecule additives and degradation products; Microorganism degraded cellulose, semicellulose, lignin and ester additives; degradation product from different component accelerated the aging, which could be exampled by the fact that HCl from degradation of PVC accelerated the hydrolyzation of cellulose and semicellulose.
