FIELD: chemistry.SUBSTANCE: invention relates to a polymer composition containing (meth)acrylic polymer and a multistage polymer, particularly a core-shell type polymer, to a method of producing a polymer composition, use thereof as a superconcentrate in thermosetting resins or thermoplastic polymers, as well as an impact-resistant composition based thereon and production thereof. Polymer composition is obtained by spray drying or coagulation.EFFECT: invention makes it possible to prevent agglomeration of polymer particles obtained by a multi-step method, homogeneous distribution thereof, to increase impact viscosity of thermosetting plastics, such as epoxy, polyester or (meth)acrylic resins or a thermoplastic matrix.32 cl, 1 dwg, 1 ex |
