The durability of polymers exposed to harsh application conditions is reduced by physical losses of stabilizers. Their physical persistence can be improved by increasing their molecular weight, without changing the action mechanism. Funtionalization of conventional polymers by grafting with monomers bearing stabilizing moieties during reactive processing, grafting during mastication, and phototriggered grafting are particularly suitable methods for synthesis of polymer‐bound stabilizers. Properties and examples of application of stabilizer‐functionalized polymers are given.
