多乙烯基单体因其方便易得、固有的反应多活性位点而一直是合成多种复杂拓扑结构聚合物的理想单体;然而Flory-Stockmayer(F-S)均相场理论及广泛的前期尝试已证实多乙烯基单体的聚合会在极低转化率(<10%)下形成凝胶,而无法进行可控聚合.近年来,可控活性聚合方法的发展为动力学控制下的多乙烯基单体聚合奠定了基础,并成功合成多种具有不同复杂结构的聚合物.特别地,合成了具有新颖拓扑结构的单链超内环化聚合物.本文综述了近年来多乙烯基单体聚合的历史,动力学控制下的可控活性聚合机理以及单链超内环化聚合物的聚合过程、结构特征、应用等,展望了该新颖结构聚合物的应用前景,并对多乙烯基单体的可控活性聚合领域的未来发展提出了建议.
Polyvinyl monomers have long been the ideal monomer for the synthesis of many complex topological polymers because of their convenient accessibility and inherently reactive multiple active sites. However, Flory-Stockmayer (FS) homogeneous phase theory and extensive prior attempts Polymerization of vinyl monomers has been shown to form gels at very low conversions (<10%) without controlled polymerization. In recent years, the development of controlled living polymerization processes has been driven by the kinetics of multi-ethylene It has laid the foundation for the polymerization of monomer and successfully synthesized many kinds of polymers with different complex structures.In particular, we synthesized single-chain hyper-cyclized polymer with novel topological structure.In this paper, The history of polymerization, the mechanism of controlled living polymerization under the control of kinetics, the polymerization process, structural characteristics, application and so on of single chain hyper-cyclized polymer, the application prospects of this novel structure polymer are prospected. Proposed the future development of the controlled activity polymerization of the body.
