Abstract: Cellulose，as an important，low cost and wide available natural products，might be the most valuable biomass resources as the substitute for petroleum. The study on chemistry of cellulose materials has been developed rapidly and has become a hot topic in recent years. In this area，the investigation of graft copolymer of cellulose has drawn great attention. In this paper，the applications and developments of the graft method for the ring-opening polymerization（ROP）of lactones and lactides with cellulose and cellulose derivatives are introduced. Furthermore，this review also includes the latest scientific research development and the future potential in this field.

Key words: cellulose, cellulose derivatives, lactones, ring-opening graft polymerization

摘要： 纤维素作为自然界最广泛、最重要、最廉价易得的天然产物，是未来有望替代石油资源的生物质资源之一，各种利用纤维素为原料的化学研究逐渐成为生物大分子等研究领域的热点。其中，针对纤维素接枝共聚物的研究受到越来越广泛的重视。本文主要从内酯经开环聚合（ROP）接枝纤维素和纤维素衍生物出发，介绍近年来这类特殊的接枝方法在纤维素改性领域的应用和发展，并对其前景进行了展望与预测。
