从引发和催化两个方面概述了光辐照在活性自由基聚合(LRP)中的应用,从机理上详细地分析了光辐照对氮氧调控自由基聚合(NMP)、原子转移自由基聚合(ATRP)、可逆加成-断裂链转移自由基聚合(RAFT)以及有机钴催化的可控自由基聚合反应(CMRP)的影响。与传统自由基聚合相比,光调控的活性自由基聚合方法可在温和的条件下生成自由基,能够克服传统LRP的一些缺陷,如降低催化反应活化能、提高聚合物末端官能度等。同时,本文对光调控反应的进一步应用以及新方法的产生也进行了展望。
The application of light irradiation in living radical polymerization (LRP) is summarized from two aspects of initiation and catalysis. The effects of light irradiation on NMP, ATRP (ATRP), reversible addition-fragmentation chain transfer radical polymerization (RAFT) and organic cobalt-catalyzed controlled radical polymerization (CMRP). Compared with traditional radical polymerization, photo-controlled living radical polymerization can generate free radicals under mild conditions and overcome some shortcomings of traditional LRP, such as reducing the activation energy of catalytic reaction and increasing the terminal functionality of the polymer. At the same time, this article also prospects the further application of photoregulation reaction and the new method.
