FIELD: technological processes.
SUBSTANCE: dispersion preparation is suggested as a result of (a) preparation of multiple nanoparticles that are characterised with average size of particles equal to 300 nanometers or less; (b) addition of nanoparticles to the mixture of one or more polymerised ethylene-nonsaturated monomers with one or more polymers that are characterised with average molecular weight from 1,000 to 20,000 with preparation of mixture; (c) effect of high shear stresses to the mentioned mixture in the presence of either organic dissolvent or water medium with formation from mixture of microparticles; and (d) polymerisation of ethylene-nonsaturated monomers under conditions of free-radical polymerisation. Stable water dispersion of microparticles is also suggested as well as variants of its application in compositions for application of coats.
EFFECT: development of efficient method of production of stable dispersion of composite microparticles for usage in compositions for application of coats.
