METHOD OF PRODUCING POWDER OF ENCAPSULATED POLYMER MATERIAL (VERSIONS) AND APPARATUS FOR REALISING SAID METHOD (VERSIONS) Russian patent published in 2012 - IPC C08J3/12 C08J3/28 C08J9/14 C08J9/00 B05D1/04 B05C3/00 B82Y99/00 

FIELD: chemistry.

SUBSTANCE: method involves forming a first two-phase stream of nano- or microparticles and a second two-phase stream of particles, charging particles and charging and dispersing the nano- or microparticles, mixing the nano- or microparticles with the second two-phase stream of charged particles and subsequent separation of the end product from the reaction products and the carrier gas. One version of the method is characterised by that a second two-phase stream of particles of a monomer and/or mixture of monomers is formed, followed by simultaneous charging of particles of the monomer and/or mixture of monomers and charging and dispersing the nano- or microparticles, wherein all particles of the monomer and/monomers are charged in a gas discharge with the same charge of the required value but of the opposite sign to that of the nano- or microparticles; the first two-phase stream of charged nano- or microparticles is mixed with the second two-phase stream of oppositely charged particles of the monomer and/or monomers and particles of the monomer and/or monomers are simultaneously deposited on the oppositely charged nano- or microparticles and a monomer layer is formed on the surface of separate nano- or microparticles and said monomer layer is polymerised; the obtained powder of the encapsulated polymer material, which is in a multi-phase gas stream, is separated from the reaction products and the carrier gas.

EFFECT: use of the present invention enables to obtain powder of encapsulated polymer material while providing the required concentration and uniformity of distribution of nano- or microparticles in the end polymer material.
