## Abstract **Summary:** Advanced ^1^H solid‐state NMR methods are applied for studying the hydrogen bond formation occurring in polymer hydrogels based on __N__‐isopropylacrylamide (NIPAAm) and methacrylic acid (MAA). For P(NIPAAm‐__co__‐MAA) copolymers collapsed at low pH, two populations of wate
