自由基螺旋聚合的研究进展

Research Progress in Radical Helical Polymerization

螺旋聚合物是一类在不对称领域具有特殊用途的高分子,可用于对映体分离、不对称催化和不对称光学等领域。其合成方法的研究一直是合成高分子科学的研究热点。自由基螺旋聚合以其大量优点备受人们重视,但受自由基聚合的自身缺陷影响,在螺旋聚合物合成上成功的例子较少。本文对自由基螺旋聚合的自身缺陷进行探讨,对各种方法进行综述,介绍了手性单体聚合、手性引发剂聚合、手性链转移聚合、手性模板控制聚合和手性溶剂聚合等各种自由基螺旋聚合方法,并对其前景进行了展望。

Helical polymer was a polymer that had special application in asymmetric fields, can be used for the separation of enantiomers, asymmetric catalysis and asymmetric optical fields, etc. The synthesis of helical polymer has been the research focus of the synthetic polymer science. Free radical polymerization with many advantages has attracted much attention in synthesis of helical polymer, but there are few successful examples because of dgfects of the free radical polymerization. In this paper, the defects of free radical helix polymerization are discussed, various methods are summarized and introduced including chiral monomers,free radical polymerization, the chiral initiator polymerization, chiral chain transfer polymerization, chiral template controling polymerization and chiral solvent polymerization, etc. Moreover, the future study prospect were proposed.
