USE OF A POLYMER COMPOSITION FOR MAKING ARTICLES WITH IMPROVED COLORABILITY AND IMPROVED SURFACE APPEARANCE Russian patent published in 2020 - IPC C08L23/14 C08L23/12 

FIELD: technological processes.

SUBSTANCE: invention relates to use of a polypropylene composition containing at least one heterophase propylene and filler for producing at least partially colored articles. Disclosed is use of polypropylene composition containing heterophase polypropylene, having content of soluble in cold xylene (SCX) fraction of ≥ 10.0 wt % and characteristic viscosity (CV) of fraction soluble in cold xylene (SCX)> 2.0 dl/g, and/or heterophase polypropylene, having content of soluble in cold xylene (SCX) fraction of ≤ 35.0 wt % and intrinsic viscosity (IV) of SCX > 4.0 dl/g, and filler, wherein the polypropylene composition has an intrinsic viscosity (IV) of the SCX of ≥ 3.0 dl/g and a ratio of characteristic viscosity (CW) of the SCX/soluble in cold xylene (SCX) fraction of ≥ 0.113 dl/g, to obtain at least partially colored articles, as well as at least partially colored article.

EFFECT: technical result is obtaining at least partially colored articles, which show both good colorability, and good appearance of surface, and to colored articles produced by means of it.
