摘要
因为独特的聚合机理,分散聚合广泛运用于制备各种聚合物微球。介绍了分散聚合的成核机理和稳定机理,综述了分散聚合在氮氧稳定自由基聚合、原子转移自由基聚合、可逆加成-断裂链转移聚合以及超临界二氧化碳聚合等方面的应用以及所制备的聚合物微球的技术现状,并对分散聚合未来研究方向进行了展望。
Dispersion polymerization is widely used in preparing various polymer microspheres because of its unique polymerization mechanism,which the nucleation mechanism and the stability mechanism are introduced.The application of dispersion polymerization in nitrogen and oxygen stable free radical polymerization,atom transfer free radical polymerization,reversible addition-fragmentation chain transfer polymerization and supercritical carbon dioxide polymerization,as well as the status of microspheres obtained from such technologies,are reviewed.The future research direction of dispersion polymerization is also prospected.
