Porous polymer microspheres have many specific applications, for example, in medicine, in the construction industry, as adsorbents, as well as additives with special mechanical and thermal properties. These microspheres are also used as additives for paints, varnishes, cosmetics or optical devices. These applications are a consequence of the physical, chemical and morphological properties of porous polymers, such as the degree of crosslinking, porosity, pore volume, modification possibilities, thermal resistance, etc. Because methacrylate polymers are characterized by high resistance to moisture, heat and chemical agents, and have good porous properties, they are often used to prepare porous polymers in the form of microspheres [1-3]. This paper presents the synthesis of microspheres based on methacrylic thioester derivative of naphthalene (2-NAF-S-Met) and DVB and analysis of thermal, spectroscopic, and porous properties of obtained microspheres. In Table 1 presented the experimental parameters of syntheses of sulfur-containing microspheres.
