摘要: 通过丙烯酸、2-甲基丙烯酸、巴豆酸与五氯苯酚的酯化反应实现了3种丙烯酸酯单体的掺杂改性合成,采用核磁共振和质谱测试技术对掺杂丙烯酸酯单体进行了表征。利用掺杂改性后的丙烯酸单体与季戊四醇四丙烯酸酯之间的共聚反应,结合超临界萃取技术,制备出理论密度为50 mg·cm-3、掺杂氯元素质量百分数平均值最高约为15%的掺杂丙烯酸酯聚合物泡沫。通过测定聚合物凝胶速率,初步探讨了掺杂丙烯酸酯单体与多元丙烯酸酯单体的共聚合反应机理。Abstract: Doped acrylate monomers were synthesized through the reaction between different crylic acid and halogenated phenylic acid, and their structure were characterized with nuclear magnetic resonance and mass spectrometry. Poly doped-acrylate foams were prepared with theoretical density of 50 mg·cm-3, and the maximal mass fraction of chlorine doped was 15% doped chlorine 15%. Based on polymer gelling velocity, the polymerization of doped acrylate monomer with poly acrylate was discussed.
