证明了使用新设计的单体五氟苯基4-马来酰亚胺苯甲酸酯成功地顺序控制安装活化酯。五氟苯基4-马来酰亚胺苯甲酸酯被动力学地安装在氮氧化物催化聚合的不同阶段，即靠近a链末端和在PS链的中间。此外，通过后聚合功能化成功地实现了非极性官能团和极性官能团的安装，这表明了合成局部官能化聚合物的通用前体的多功能性。
The successful sequence-controlled installation of an activated ester using a newly designed monomer pentafluorophenyl 4-maleimidobenzoate is demonstrated. Pentafluorophenyl 4-maleimidobenzoate is kinetically installed at different stages of a nitroxide-mediated polymerization, namely, near the a-chain end and in the middle of a PS chain. In addition, successful installation of apolar and polar functional groups is achieved via post-polymerization functionalization, which demonstrated the versatility of the synthesis of a universal precursor for locally functionalized polymers.
