Control of gradient copolymer composition in ATRP using semibatch feeding policy

Abstract Controlled/living radical copolymerization (CLRcoP) operated in a batch process is subject to composition drifting and thus produces spontaneous gradient copolymer. The composition distribution along the chain length of individual chains is solely determined by the reactivities of comonomers and the as‐synthesized product is uncontrolled. Design of the composition vs. chain length profile provides a new route for developing polymer …
