<jats:p>In this contribution, the use of glycidyl methacrylate and styrene copolymers synthesized by nitroxide‐mediated polymerization (NMP) as chain extenders of postconsumer poly(ethylene terephthalate) waste (r‐PET) is described. Our observations revealed that the copolymers synthesized by NMP act as efficient chain extenders for the regeneration of PET waste. Epoxide groups in the copolymers react with PET end reactive groups producing chain extended PET with higher molecular weight and improving performance.
