FIELD: chemistry.
SUBSTANCE: composition contains an aqueous dispersion of polymeric microparticles, in which the polymeric microparticles contain (a) a copolymer obtained through polymerisation of one or more ethylene-unsaturated monomers in an aqueous medium in the presence of a macromonomer which contains alternating donor and acceptor links and does not contain segments of maleate and fumarate monomers, Lewis acids and transition metals; (b) nanofiller (20-90 wt %) and (c) optionally a plasticiser.
EFFECT: composition can be deposited using any method, including spraying, where the obtained coating dries fast, has virtually no mud cracking defects and has excellent sound and vibration damping properties.
