Abstract

AbstractA novel class of backbone‐hydrolyzable LCST‐type polyesters of poly(oligo(ethylene glycol) bis(glycidyl ether)‐alt‐ketoglutaric acid)s (PEmKs) with numerous reactive sites is presented in this study. The target polyesters are prepared with commercially available hexa(ethylene glycol) bis(glycidyl ether) (E6BG), ethylene glycol bis(glycidyl ether) (E1BG), and 2‐ketoglutaric acid (KGA). By varying the initial feed ratio of E6BG and E1BG and the polymer concentration, a tunable thermal responsiveness with excellent repeatability is achieved.
