Postpolymerization modification of commodity polymers has emerged as a powerful strategy for synthesizing functional that are challenging to obtain via direct polymerization. Moreover, it offers opportunities upcycle existing and enhance their material properties. In this work, we introduce photocatalytic decarboxylative Heck-type approach polyacrylates. By employing an acridine-based photocatalyst in combination with cobaloxime catalyst, hydrolyzed polyacrylates varying carboxylic acid contents were efficiently converted into bearing olefin functionalities. The degree incorporation notably influenced the thermal properties resulting materials. Importantly, protocol is applicable broad range vinyl comonomers, yielding 1,3-diene copolymers exclusive 1,2-insertion selectivity. Furthermore, variety terminal alkenes can be utilized functionalize acrylate copolymers, subsequent thiol-ene click reactions further expand versatility accessible polymers.
