活性可控自由基聚合在天然高分子改性领域的应用研究

The Application of Activated Controlled Radical Polymerization in the Modification of Natural Polymer

活性可控自由基是合成可设计性微观结构和相对分子质量分布较窄聚合物的一种方法。综述了活性可控自由基聚合中的ATRP、FART、NMRP的聚合机理及其在天然高分子(纤维素、壳聚糖、淀粉等)改性领域的应用,在此基础上对活性可控自由基聚合进行了小结并对其以后的发展方向进行了展望。

The activated controlled radical polymerization provides a route for synthesizing polymers with designed microstructure and narrow molecular weight distributions. The ATRP, FART, NMRP polymerization mechanism of activated controlled radical polymerization and its applications in the modification of natural polymers （cellulose, chitosan and starch, etc.）are reviewed. On these basis, the activated controlled radical polymeriza-tion is summarized and its future development is discussed.
