开发新型聚合反应以获得结构新颖的聚合物是高分子科学基础研究的重要领域。乙烯磺酰基化合物的Michael反应具有点击高效的特征，但是目前为止其相应的聚合体系却没有得到充足的发展。本项目旨在建立发展乙烯磺酰基化合物的点击聚合方法：拓展乙烯砜-硫醇、乙烯砜-胺的聚合体系，建立乙烯磺酸酯-硫醇、乙烯磺酸酯-胺、乙烯磺酰胺-硫醇与乙烯磺酰胺-胺的聚合体系。从单体设计出发，优化点击聚合过程，开发高效有机催化体系，合成结构明确、分子量高、溶解性好的线形和超支化聚合物。在建立新型聚合方法的同时，发展一系列结构新颖的磺酰基聚合物，包括聚（硫醚-砜）、聚（胺-砜）、聚（硫醚-磺酸酯）、聚（胺-磺酸酯）、聚（硫醚-磺酰胺）和聚（胺-磺酰胺），并探究其热转变行为、折光性能和氧化还原性质，深刻阐释其结构性能关系。该项目的研究，有望促进乙烯磺酰基化合物聚合方法的建立并推动磺酰基高分子材料的发展。

The development of novel polymerization reactions is fundamentally important in polymer science. In this context, the Michael reactions of vinylsulfonyl compounds have the characteristics of ‘click’ reactions and thus show great potential to be tailored for polymer synthesis. However, the corresponding polymerization methodology has not been well-developed. This project aims to establish the ‘click’ polymerization system of vinylsulfonyl compounds, that is, to expand the polymerization systems of vinylsulfone-thiol and vinylsulfone-amine, and to establish the polymerization systems of vinylsulfonate-thiol, vinylsulfonate-amine, vinyl sulfonamide-thiol and vinylsulfonamide-amine. Starting from monomer design, we will develop efficient organocatalysts, optimize the polymerization conditions, and synthesize linear/hyperbranched polymers with good solubility, high molecular weight and well-defined chemical structures. At the same time, a series of novel sulfonyl polymers will be developed, including poly(β-thioether sulfone), poly(β-amino sulfone), poly(β-thioether sulfonate), poly(β-amino sulfonate), poly(β-thioether sulfonamide), and poly(β-amino sulfonamide). Their thermo, refractive and redox properties will be thoroughly investigated, and their structure-property relationship will be explained in detail. The research of this project is expected to establish the click polymerization methodology of vinylsulfonyl compounds and also open up new opportunities for developing sulfonyl polymer materials.
