中性甲基丙烯酸酯单体在铜催化的原子转移自由基聚合(ATRP)条件下，在甲醇中发生酯交换反应，生成多种副产物。副反应发生在一系列亲水的甲基丙烯酸酯中，但有些可以通过使用高级醇来减少。这项研究表明，当使用乙醇溶剂通过铜催化的传统ATRP合成具有结构和组成纯的甲基丙烯酸酯(Co)聚合物时，必须小心。
Neutral methacrylate monomers undergo transesterification in methanol to produce multiple by-products under copper-catalyzed atom transfer radical polymerization (ATRP) conditions. The side-reactions occur for a range of hydrophilic methacrylates but some may be reduced by employing higher alcohols. This study demonstrates that care must be taken when using alcohol solvents for the synthesis of architecturally and compositionally pure methacrylate (co)polymers via copper-catalyzed conventional ATRP.
