摘要

摘要 研究了在紫外线照射下,以吩嗪为光催化剂的甲基丙烯酸甲酯自由基聚合的特点。研究发现,以吩嗪为基础的组合物可以引发甲基丙烯酸甲酯聚合,在某些情况下,还可以在受控条件下进行聚合。研究表明,通过调整酚嗪+有机溴化合物+叔胺催化体系的组成,可以制备出分子质量范围足够宽的聚甲基丙烯酸甲酯,得到的聚合物还可以通过嵌段共聚进一步改性。所建议的催化组合物的一个具体特点是,可以使用低浓度催化剂合成高转化率的聚合物,并且无需事先对反应混合物进行脱气处理。

Radical Polymerization of Methyl Methacrylate in the Presence of Phenazine as Photocatalyst

The features of radical polymerization of methyl methacrylate involving phenazine as photocatalyst, under UV irradiation, have been investigated. It has been found that the phenazine-based compositions allow initiation of the methyl methacrylate polymerization and, in certain cases, performing it in a controlled regime. It has been shown that it is possible to prepare poly(methyl methacrylate) over sufficiently wide range of molecular mass by adjusting the composition of the phenazine + organobromine compound + tertiary amine catalytic system, the obtained polymer being prone to further modification via block copolymerization. A specific feature of the suggested catalytic compositions is the possibility of the polymer synthesis to high conversion using a low concentration of the catalyst and without prior degassing of the reaction mixture.
