FIELD: technological processes.
SUBSTANCE: present invention relates to the technology of modifiers production on the basis of nuclear-shell type particles used for production of molding such as films, pipes, mirror housings etc. from poly(meth)acrylates. The nuclear-shell type particle consists of a nucleus, the first shell and, if required, the second shell that on every single case consist of alkylmetacrylate and styrene recurring units with minimum glass-transition temperature of 30°C. The said particles are produced by multistage emulsion polymerisation.
EFFECT: invention ensures implementation of the process with minimum labour costs and small investments for commercial deployment.
