The water‐soluble copolymers having pendant terthiophene, poly(AA3T‐ co ‐AA), were synthesized by radical copolymerization of [(2,2′ : 5′,2′′‐terthiophen‐5‐yl)methyl acrylate] (AA3T) and acrylic acid (AA), and their molecular structures and thermal behaviors were studied. X‐ray diffraction study showed that the copolymers containing a certain amount of AA3T can form the crystals with monolayer structure, while incorporation of too many AA units into the copolymers disrupted this structure. Possible mechanism of self‐doping on heating was discussed in terms of interaction between AA3T unit with AA unit in the copolymers.
