A novel class of backbone‐hydrolyzable LCST‐type polyesters of poly(oligo(ethylene glycol) bis(glycidyl ether)‐ alt ‐ketoglutaric acid)s (PE m Ks) with numerous reactive sites is presented in this study. The target polyesters are prepared with commercially available hexa(ethylene glycol) bis(glycidyl ether) (E 6 BG), ethylene glycol bis(glycidyl ether) (E 1 BG), and 2‐ketoglutaric acid (KGA). By varying the initial feed ratio of E 6 BG and E 1 BG and the polymer concentration, a tunable thermal responsiveness with excellent repeatability is achieved.
