The results showed that during the chemical pretreatment the guaiacyl unit was more readily to be sulfonated and dissolved, and there were new conjugated carbonyl and quinoidstructure formed.
结果表明，预处理过程中愈创木基易于磺化和溶出，木素中有新的共轭羰基和醌型结构产生。

The products with higher conductivity are mainly 1, 4-connected head-to-tail chain structure, both benzenoid and quinoid units exist in the polymer chain.
