研究了低卡伯值未漂硫酸盐阔叶木浆在过氧化物酶体系存在下，与松柏醇葡萄糖苷及果胶发生共聚反应，生成脱氢聚合物（DHP）及DHP-碳水化合物复合体，并利用13 C-NMR分析了DHP-碳水化合物复合体的结构。结果表明：DHP-碳水化合物复合体中DHP结构单元之间主要通过β -O-4、α -O-4、β-β 、β -5和β -1方式相连接，DHP结构单元还通过苯甲醚键、苯甲酯键和少量缩醛键与纸浆纤维和果胶相连。纤维胞间层经过修复后，纸张的强度有明显提高。纸张的干强度和湿强度分别提高37.5%和166.3%。木素前驱物可以与果胶及纸浆纤维中的多糖有效地发生共聚，使得纤维复合胞间层得到修复，因而提高纸张强度。

DHP-碳水化合物复合体
The dehydrogenation polymer(DHP) and the DHP-carbohydrate complexes are prepared through the co-polymerization of the unbleached kraft pulp of low kappa number from hardwood and coniferin or coniferin/pectin in the presence of the lignin peroxidase. The 13 C-NMR determination shows that the main substructures of the obtained DHP are β -O-4, α -O-4, β-β , β -5 and β -1 structures. Furthermore, it is also found that the DHP is linked with the pectin and the fibers of the kraft pulp by typical LCC linkages, i.e. the benzyl ether bonds, the ester bonds, and a small amount of ketal bonds. As a result, the paper strength is increased significantly after the rebuilding of the CML structure of the fibers. The dry and wet tensile strengths of the paper web are increased by 37.5% and 166.3% after treatment with the coniferin and the pectin. It is demonstrated that the lignin precursor can be co-polymerized with the pectin and the polysaccharides in the pulp fiber efficiently, to obtain the rebuilt CML, which binds the pulp fibers and therefore enhances the paper strength.
