摘要
可控/活性自由基聚合是近年来发展的温和、聚合反应进程可控、分子结构可设计性强的自由基聚合反应技术,其核心在于活性自由基中间体与催化剂/链转移剂的可逆活化/失活过程,常用于极性单体聚合制备结构多样的有机高分子材料.镍催化剂具有多变的中心金属价态及多样的聚合反应机理,在可控/活性自由基聚合领域存在独特的优势.对近年来原子转移自由基聚合(ATRP)和有机金属控制的活性自由基聚合(OMRP)中的镍催化剂结构、聚合反应机理、反应行为和产物结构特征进行了综述,并对镍催化的可控/活性自由基聚合未来发展方向和应用前景进行了展望.
Abstract
Controlled/living radical polymerization reactions are developed to take the advantages of mild reaction conditions,well controlled reaction processes and accessible modification of polymer structures to build a variety of organic polymer materials with polar monomers as the starting materials in recent years,of which the fundamental mechanism is the reversible activation/deactivation between radical intermediates and transition-metal catalysts/chain transfer reagents.Because of the different oxidation states and the variable polymerization mechanisms,nickel catalysts have unique advantages in controlled/living radical polymerization.This article reviews the structure of catalysts,polymerization mechanisms and the structure of products of nickel catalyzed atom-transfer radical polymerization(ATRP)and organometallic mediated radical polymerization(OMRP).The future development direction and application prospects of controlled/living radical polymerization are prospected.
