The objects of research are nanocomposites of copolymers with organomodified montmorillonite nanoclay. The aim of the research is to develop scientific approaches to the creation of new intumescent coatings containing nanoclays, with improved flame retardant, ecological and operational characteristics through the study of the formation of nanocomposites of nanoclay with a polymer matrix. Methods of investigation-IR spectroscopy and X-ray phase analysis were used to identify the nanocomposites obtained. A procedure has been developed, synthesis and identification of nanocomposites of copolymers of ethylene with vinyl acetate and styrene with isobutyl methacrylate have been carried out. The general changes in the physicochemical characteristics of the polymer during the transformation into a nanocomposite have been established: the shift of the C = O group absorption band to the shorter-wave region, an increase in the decomposition temperature as compared with polymer matrices, and an increase in the interlayer distances in layered silicates upon transition from an organoclay to a nanocomposite. The practical significance of the work lies in the possibility of creating a formulation of a nanostructured intumescent system with nanoclay by forming nanocomposites "polymer matrix-nanoclay" in situ..
