The cocrystallization behavior of poly( n ‐octadecyl methacrylate) (POMA) and its blends with corresponding fatty acid ( n ‐octadecanoic acid) (C 18 ) was explored by differential scanning calorimetry (DSC) and X‐ray diffraction studies. The DSC curves for blended samples of POMA with C 18 show the characteristic melting endotherms that correspond to the melting of the cystallites. The existence of hexagonally packed crystalline lattice is confirmed from the X‐ray diffraction studies. Thermal degradation of the polymer and its blend proceeds in a one‐step reaction. © 2007 Wiley Periodicals, Inc. J Appl Polym Sci 104: 1226–1231, 2007
