硫醇（RSH）自由基加成到聚[2-（3-丁烯基）-2-恶唑啉]上可以通过活性/受控的阳离子异构化聚合来获得，可以在不存在副反应的情况下顺利进行，表现出点击反应的特征。“硫代点击”反应可以在可行的（[RSH]/[C=C]类似于1.2-1.5，无过渡金属添加剂）和温和的条件（在室温下用UV光产生自由基）下进行，并在一天内完成。疏水性含氟聚合物可以以与水溶性（共）聚合物或含糖共聚物相同的方式从容易获得的材料开始制备。
The radical addition of mercaptans (RSH) onto poly [2-(3-butenyl)-2-oxazoline], which is available through a living/controlled cationic isomerization polymerization, can proceed smoothly in the absence of side reactions, exhibiting the characteristics of a click reaction. The "thio-click" reaction can be performed under feasible ([RSH]/[C=C] similar to 1.2-1.5, no transition metal additives) and mild conditions (generation of radical's with UV light at room temperature) and goes to completion within a day. Hydrophobic fluoropolymers can be prepared in the same way as water-soluble (co-)polymers or glycopolymers, starting from readily available materials.
