FIELD: chemistry.
SUBSTANCE: invention concerns complex acrylic silicon rubber polymer, method of its obtainment and application. Complex acrylic silicon rubber polymer features nucleus-core-shell structure, where vinyl monomer and hydrophilic monomer are linked on a nucleus; complex acrylic silicon core has interpenetrating grid structure where silicon rubber particles are dispersed with acrylic rubber during linking, and is formed on nucleus in dispersion medium. Shell is obtained by graft polymerisation of C1-C4-alkylmetacrylate on complex acrylic silicon core with interpenetrating grid.
EFFECT: obtaining complex acrylic silicon rubber polymer with excellent impact strength, weather resistance and shine, which can be efficiently applied as impact strength modifier of vinylchloride resin.
