ABSTRACT A simple strategy is proposed to offer styrene (St) copolymer with intrinsic and catalyst‐free upcycling capability by incorporating α ‐methylstyrene (AMS) units into the poly(AMS ‐co‐ St) (PAS). Compared polystyrene (PS), PAS more susceptible depolymerizing St AMS monomers higher yields at relatively lower temperature. The yield of liquid chemicals PAS‐4 (26.1 mol% AMS) up 93 wt% 380°C, whereas that PS as control 78 wt%. reclaimed contain 58.4 37.7 AMS, while 81.8 4.1 AMS. introduction in leads a reduction other than monomers. blends PAMS do not demonstrate synergistic effect regarding facilitating depolymerization. In addition, properties new PASs prepared are comparable those virgin PASs. This work proves concept recycling efficiency could be boosted liable structural chains demonstrates closed‐loop up‐cycling.
