A novel one‐step synthesis of hydrophobically modified polyacrylamide (PAAm) is described. Triblock copolymers of poly(ethylene oxide) (PEO) and poly(propylene oxide) (PEO‐PPO‐PEO) are grafted onto PAAm in melts of acrylamide in the presence of benzoyl peroxide. The resulting PEO‐PPO‐PEO‐ g ‐PAAm graft copolymers are capable of self‐assembly in response to temperature changes in aqueous media.
