The morphology of solid phase products of thermal transformation of transition metal acrylates or its cocrystallites is studied. The thermal transformation of the metal-containing monomers studied consists in dehydration, solid phase polymerization and thermolysis process. The topography of the initial compounds and solid phase products of thermal decay, as well as their composition, are analyzed by optical and electron microscopies. The average particle sizes, d_{EM}, are: 6.0-13.0 nm in the case of FeAcr_6 (based on the data of electron diffraction, the main product is Fe_3O_4), 6.0 nm for FeCoAcr_8 and Fe_2CoAcr_{14} (Fe_3O_4, CoO, Fe_2CoO_4), and 6 nm for CoMal_2 (CoO). The material formed consists of nanosized metal particles uniformly allotted in polymer matrix.
