摘要: 木质素作为植物中蕴藏量仅次于纤维素的高聚物,是一种廉价易得、储量丰富、环境友好的可再生天然资源,但至今仍没有被充分利用。本文回顾了国内外木质素在高分子领域应用的一些探索性研究,主要介绍木质素制备木质素酚醛树脂胶粘剂、合成聚氨酯、与环氧化合物聚合以及与烯类单体接枝共聚等研究进展。这些研究虽然取得一些成果,但要把木质素作为高分子工业的基本原料之一加以利用尚有较大距离。人们越来越认识到,设法降低木质素分子的多分散性和提高反应活性可能是取得重大进展的关键所在。

Abstract: Lignin, which exists as high polymer in plant, is a sort of environment friendly and reproducible natural resource, whose reserves in the world is next to cellulose.However, man has not made the most of it as yet.This article reviews the exploratory development of utilizing lignin in macromolecule field, which mostly includes synthesizing lignin phenol formaldehyde resin adhesives, polyurethane, polymerizing with epoxide as well as graft copolymerizing with vinyl monomer.Although these studies have taken some positive results, there is still the technology gap to carry through upon using lignin as one of raw material in high polymer industry.It has been gradually realized that measures to decrease the polydispersity and increase the reactivity of lignin may be the key to achieve the breakthrough in this field.

Key words: lignin, polymer, graft copolymerization
