Progress of Reversible Deactivation Radical Polymerization (RDRP) with Alkyl Iodide

碘代化合物存在下的可逆-失活自由基聚合(reversible deactivation radical polymerization,RDRP)具有反应条件温和、体系组成简单、单体适用范围较广的优点。本文主要概述了近年来碘代化合物存在下的可逆-失活自由基聚合,主要包括退化链转移自由基聚合(degenerative chain transfer radical polymerization,DTRP)、反向碘转移聚合(reverse iodine transfer polymerization,RITP)、可逆链转移催化聚合(reversible chain transfer catalyzed polymerization,RTCP)和可逆络合聚合(reversible complexation mediated polymerization,RCMP)。概述了各种聚合方法的基本原理、适用的单体、化合物结构与活性的关系以及一些重要的副反应等。此外,还对利用各种聚合方法进行的大分子设计合成和非均相聚合研究工作做了简要的介绍。

Attractive features of reversible deactivation radical polymerization （RDRP） with alkyl iodide include simple system composition like those in conventional radical polymerization, mild reaction condition and great monomer versatility. This paper summarized the RDRP using iodocompounds in recent years, including four kinds of powerful RDRP technique： degenerative chain transfer radical polymerization （DTRP）, reverse iodine transfer polymerization （RITP）, reversible chain transfer catalyzed polymerization （RTCP） and reversible complexation mediated polymerization （RCMP）. This paper gave a general overview about the basic principle of polymerization reaction, applicability to different monomers, the relationship of reactivity with important compounds and some side reactions. Progress made in each technique related to the synthesis of polymers with different architectures, expanding polymerization in aqueous media was also briefly discussed.
