USE OF HIGH RUBBER IMPACT MODIFIERS IN THERMOPLASTIC FORMULATIONS Russian patent published in 2019 - IPC C08L27/06 C08L51/04 

FIELD: manufacturing technology.

SUBSTANCE: invention relates to a thermoplastic composition containing a thermoplastic resin based on polyvinyl chloride and from 1.0 to 3.0 parts of a core-shell impact modifier per 100 parts by weight of the thermoplastic resin, wherein the core-shell impact modifier has a rubber content of at least 90 wt.%, moreover, the particles of the core-shell impact modifier are not more than one population of particles having equal particle diameters, and are selected from the group consisting of copolymers of methacrylate-butadiene-styrene (MBS), copolymers of acrylonitrile-butadiene-styrene (ABS), core-shell acrylic polymers (AIM) and combinations thereof, as well as to a method for obtaining this thermoplastic composition and to the products obtained using this method.

EFFECT: use of impact modifiers with a high rubber content in thermoplastic compositions has been proposed.
