摘要

以甲基丙烯酸甲酯聚合为例，研究了可见光照射下常温下[亚甲基蓝+ 2-溴异丁酸乙酯]催化体系下聚合物合成的特点。估计了聚合条件(包括光照射波长和各种结构活化剂)对聚合物单体转化率和分子量特性的影响。结果表明，在温和的温度条件下，聚合可以根据原子转移机理(金属自由原子转移自由基聚合)在可控模式下进行，在低光催化剂浓度下实现高转化率。

Features of Methyl Methacrylate Polymerization Mediated by Methylene Blue and Ethyl 2-Bromoisobutyrate under Photoirradiation Conditions

Using methyl methacrylate polymerization as an example, the features of polymer synthesis in the presence of the catalytic system [methylene blue + ethyl 2-bromoisobutyrate] at room temperature under visible light irradiation are investigated. The effect of polymerization conditions, including the light irradiation wavelength and various structure activators, on the monomer conversion and molecular weight characteristics of polymers is estimated. It is shown that polymerization can proceed in the controlled mode under mild temperature conditions according to the atom transfer mechanism (Metal Free Atom Transfer Radical Polymerization) to high conversions at low photocatalyst concentrations.
