ADDITIVE COMPOSITIONS AND THERMOPLASTIC POLYMER COMPOSITIONS CONTAINING THEM Russian patent published in 2015 - IPC C08K5/00 C08K5/20 C08J3/20 C08L101/00 

FIELD: chemistry.

SUBSTANCE: invention refers to additive compositions and thermoplastic polymer compositions containing them. A method for producing the thermoplastic polymer composition involves the stages of providing a thermoplastic polymer and an additive composition separately, and then mixing the thermoplastic polymer and additive composition; the additive composition contains a clearing agent specified in a group consisting of tris-amides, aluminium 2,2'-methylene bis-(4,6-di-tert-butylphenyl) phosphate, lithium 2,2'-methylene bis(4,6-di-tert-butylphenyl) phosphate, mononcarboxylate compounds and acetal compounds, and a colouring agent; the colouring agent is present in the composition in an amount to produce the yield amount CIE L*, a*, and b*, and falling within the certain colour space. Another version for producing the thermoplastic polymer composition involves the stages of providing the thermoplastic polymer, clearing agent and colouring agent, and mixing the thermoplastic polymer clearing agent and colouring agent; the colouring agent is present in the composition in the amount to produce the yield amount CIE L*, a*, and b* falling within the certain colour space.

EFFECT: invention enables improving the physical properties of the thermoplastic polymers.
