Lewis pair cooperation provides a facile approach for polymerizing dissymmetric divinyl polar monomers such as 4-vinylbenzyl methacrylate in excellent regioselectivity and high reactivity at mild conditions, affording soluble polymers bearing pendant active vinyl groups with high molecular weight (up to 6.4 × 10 g/mol) and narrow polydispersity (PDI < 1.5). ESI-TOF MS study demonstrated that the polymerization process only concerned the methacrylic double bond and selectively remained the pendant allylic or styrene C═C bond.
路易斯酸碱对协同作用提供了一种简便的方法，可在温和条件下以优异的区域选择性和高反应活性聚合不对称二乙烯基极性单体，如甲基丙烯酸4-乙烯基苄酯，得到带有侧链活性乙烯基基团的可溶性聚合物，其具有高分子量（高达6.4×10 g/mol）和窄的多分散性（PDI < 1.5）。电喷雾电离飞行时间质谱（ESI-TOF MS）研究表明，聚合过程仅涉及甲基丙烯酸双键，并选择性地保留侧链烯丙基或苯乙烯碳-碳双键。
