分别合成了带有2-脲-4[1 H]-嘧啶酮(UPy)基团的单体 SCMHBMA 和带有烷基侧链的烯类单体A6ACA,两种单体聚合最终得到分子链间通过四重氢键联接的新型网状聚合物。利用红外光谱(IR)、核磁共振氢谱(1 H NMR)、质谱表征了单体及最终产物结构；通过差示扫描量热分析(DSC)和热重分析(TGA)对合成产物热性能进行了表征,表明产物熔点低,热稳定性略低；动态热机械分析(DMA)和拉伸测试表明产物呈现良好的柔韧性、力学性能良好的弹性体性质。

Monomer of SCMHBMA with 2-ureido-4 [1 H ]-pyrimidone (UPy)group and monomer of A6ACA with alkyl group were synthesized.Novel quadruple hydrogen-bonding supramolecular network polymer was polymerized from the two monomers.The structures of monomers and polymer were characterized by infrared spectrum (IR),hydrogen nuclear magnetic resonance (1 H-NMR)and mass spectrum.Thermal properties were investigated by differential scanning calorimeter (DSC),and thermogravimetric analysis (TGA).It was proved that the product has low melting point and moderate thermal stability.The product behaves like elastomer with good toughness and mechanical properties.
