## Abstract The aqueous solutions of triblock copolymers of poly(ethylene glycol)–poly(ϵ‐caprolactone‐__co__‐glycolide)–poly(ethylene glycol) [PEG–P(CL‐GA)–PEG] undergoing sol–gel transition as the temperature increases from 20 to 60°C were successfully prepared. The thermogelling block copolymers
## Abstract In this article, a novel biodegradable and pH‐sensitive hydrogel based on polycaprolactone, poly(ethylene glycol) and methylacrylic acid (MAA), was prepared by UV‐initiated free radical polymerization. The obtained hydrogel was characterized by ^1^H NMR and FTIR. The acute toxicity test
