A novel clay‐dispersed ABA (PSe‐PMMA‐PSt) triblock copolymer nanocomposite was synthesized by atom transfer radical polymerization (ATRP). The resulting material showed an expansion of interlayer distance and higher thermal stability. The molecular weight (MW) and the molecular weight distribution (MWD) can be controlled. Exfoliated nanocomposite was achieved as revealed by X‐ray diffraction (XRD) and transmission electron microscopy (TEM). It was found that the addition of only a small amount of organo‐clay was enough to improve the thermal stabilities and properties of nanocomposite. POLYM.
