摘　　要：低卡伯值未漂硫酸盐阔叶木浆与松柏醇葡萄糖苷在过氧化物酶体系存在下可发生聚合反应,生成脱氢聚合物(DHP)及DHP-碳水化合物复合体。用红外光谱和高分辨率CP/MAS13C-NMR对DHP-碳水化合物复合体结构进行分析。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、β-β、β-5和β-1方式连接,DHP结构单元还通过缩醛键、苯甲酯键和苯甲醚键与浆中碳水化合物相连;经过松柏醇葡萄糖苷处理后,纸张的干强度提高不大,但湿强度为空白样的2.1倍。Dehydrogenation Polymer （DHP） and DHP-Carbohydrate Complexes were prepared through polymerization of low kappa number unbleached kraft hardwood pulp and coniferin in existence of peroxidase system. FT-IR and CP/MAS 13C-NMR were used to analyze the structure of DHP-carbohydrate complexes. It was found that DHP-carbohydrate complexes, which could produce crosslinking between fibers, were formed on the surface of fibers. The structural units of DHP-carbohydrate complexes were connected byβ-O-4,β-β,β-5 andβ-1 structures. Furthermore, DHP was also linked with fibers of kraft pulp by acetal linkages, benzyl ether linkages and ester bonds. Dry strength of paper was not enhanced obviously after kraft pulp was treated with coniferin, but the wet strength was increased by 2. 1 times as the blank sample.
