将链烯基硼酸酯单元掺入聚（甲基丙烯酸甲酯）作为主链降解的触发位点。氟阴离子与硼侧基的络合和随后的锰盐活化通过在相邻的甲基丙烯酸酯单元中产生主链碳自由基和β-断裂引发降解。此外，邻苯二酚是必需的，大概螯合配位的锰中心是至关重要的降解。
Alkenylboronate units were incorporated into poly(methyl methacrylate) as trigger sites for backbone degradation. The complexation of a fluoride anion to the boron pendant and subsequent activation by a manganese salt triggered the degradation through the generation of a main-chain carbon radical and β-scission in an adjacent methacrylate unit. The addition of catechol was required, and presumably the chelate coordination to the Mn center was crucial for the degradation.
