Abstract Using differential scanning calorimetry, the structure of the diblock copolymer (DBC)MePEO‐ b ‐PAAm was determined. The behaviour of DBCs in water and mixed solvents was investigated. It is shown that adding of dimethyl formamide to DBC water solutions leads to destruction of the H‐bonds network between the PAAm and MePEO blocks. The tendency of DBCs to micellization in water/ethanol mixture depends on the length of MePEO block and grows with increasing molecular weight of MePEO and PAAm.
