COMPOSITION, THERMOPLASTIC RESIN COMPOSITION CONTAINING SAID COMPOSITION, AND MOULDED ARTICLE FROM SAID THERMOPLASTIC RESIN COMPOSITION Russian patent published in 2021 - IPC C08K5/09 C08K5/98 C08K5/523 C08L23/12 

FIELD: chemistry.

SUBSTANCE: invention relates to a composition for use in a thermoplastic resin composition. Composition contains the following components (A), (B), (C) and (D), wherein the proportions of the corresponding components relative to the total amount of (A) + (B) + (C) + (D) are: (A) 35–75 wt. %, (B) 10–40 wt. %, (C) 0–20 wt. % and (D) 5–35 wt. %. At that, (A) - aromatic phosphate metal salt, represented by following formula (1):

,

in which each of R¹-R⁴ independently represents a hydrogen atom or a linear or branched alkyl group containing 1 to 9 carbon atoms; R⁵ is an alkylidene group containing 1 to 4 carbon atoms; m is a number equal to 1 or 2; when m equals 1, M¹ represents lithium; and when m is equal to 2, M¹ is hydroxyaluminium; (B) is sodium carboxylate; (C) is a metal salt of a fatty acid represented by following formula (2):

,

in which R⁶ is a group introduced into an aliphatic organic acid containing 10 to 30 carbon atoms; M² is an n-valent metal atom (provided that the sodium atom and the calcium atom are excluded); and n is integer from 1 to 2; and (D) a fatty acid. Also disclosed is a thermoplastic resin composition and a moulded article.

EFFECT: disclosed composition has excellent fluidity and is capable of imparting excellent transparency and physical properties to thermoplastic resins.
