Functional polymers remain at the core of polymer science in the second century of macromolecular material research. Lactones are known as monomers for ring-opening polymerizations; however, polymers containing lactone rings as pendant groups are rare. In this study, we revive an overlooked monomer, mevalonic lactone methacrylate, by demonstrating its radical polymerization, reporting the properties of the polymer product, and providing information on the thermal, UV, and hydrolytic stabilities of both the monomer and polymer. Controlled polymerization (via RAFT) provides synthetic precision and active terminal groups; thus, the formation of a simple block copolymer based on the aforementioned polymer is presented. The pendant ring accepts nucleophilic attacks, so the initially hydrophobic polymer can be altered to make it hydrophilic via reactions with nucleophiles in just seconds. Thus, the polymer film provides responsive surface formation.

关于甲羟戊酸内酯甲基丙烯酸酯的光聚合：暴露被忽视单体的潜力

在大分子材料研究的第二个世纪，功能聚合物仍然是聚合物科学的核心。内酯被称为用于开环聚合的单体；然而，含有内酯环作为侧基的聚合物很少见。在这项研究中，我们通过展示其自由基聚合、报告聚合物产品的性质并提供有关单体和聚合物的热稳定性、紫外线稳定性和水解稳定性的信息，重振了一种被忽视的单体甲羟戊酸内酯甲基丙烯酸酯。可控聚合（通过RAFT) 提供合成精密和活性端基；因此，提出了基于上述聚合物的简单嵌段共聚物的形成。悬垂环接受亲核攻击，因此最初疏水的聚合物可以在几秒钟内通过与亲核试剂的反应而改变，使其亲水。因此，聚合物膜提供响应性表面形成。
