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。
Actively controllable free radicals are a way of synthesizing designer microstructures and relatively narrow molecular weight distribution polymers. The polymerization mechanism of ATRP, FART, NMRP and their application in the modification of natural polymers (cellulose, chitosan, starch, etc.) were reviewed. On the basis of this, The basic polymerization is summarized and the future development direction is forecasted.
