METAL-IONOMER POLYMERS Russian patent published in 2019 - IPC G03G9/113 

FIELD: chemistry.

SUBSTANCE: disclosed group of inventions relates to polymerisation methods comprising styrene/acrylate polymer resins with a metal ion used, for example, in organic/inorganic nanoparticles from core and shell, for example with shell containing ionomer, which can be used to produce toner. Disclosed group of inventions includes a composite nanoparticle, a latex containing a composite nanoparticle and an article containing latex. Composite nanoparticle contains: a core containing a styrene/acrylate polymer resin of a core, optionally containing a metal, and a shell containing a metal-ionic ionomer resin, wherein the metal-ionic ionomer resin containing said shell contains a styrene/acrylate polymer which contains a silver acrylate monomer which is added to the styrene/acrylate polymer by polymerisation.

EFFECT: technical result consists in providing composite materials which can be used to produce articles, such as sensors, materials with variable electronic properties in solvents, optical limiters and filters, as well as optical data storage, wherein plasmon properties of metals provide for the possibility of bio-imaging, since, unlike ordinary fluorescent dyes, nanodispersed metal is not photorefigurated and can be used to control dynamic phenomena for a long period of time.
