COMPOSITION, THERMOPLASTIC RESIN COMPOSITION CONTAINING THE SAME AND MOULDED ARTICLE MADE OF THE SAME Russian patent published in 2023 - IPC C08K5/521 C08K5/98 C08L23/10 

FIELD: thermoplastic resin.

SUBSTANCE: present invention is related to a thermoplastic resin additive composition, a thermoplastic resin composition containing the same, and a molded article made of the same. A composition of additives for a thermoplastic resin, where the thermoplastic resin is a polypropylene-based resin, contains: (A) an aluminum salt of a cyclic organophosphorus acid represented by Formula (1) below, wherein R¹ to R⁴ each independently represents a tert-butyl group and R⁵ represents a methylene group; and (B) sodium carboxylate, where the molar ratio between (A) the aluminum salt of the cyclic organophosphorus acid represented by formula (1) and (B) the sodium carboxylate (A)/(B) is in the range of 0.30 to 0.56.

Thermoplastic resin compositions for making molded articles containing a thermoplastic resin additive composition such that the compound of structural formula (A) is contained in an amount ranging from 0.001 to 10 parts by weight relative to 100 parts by weight of polypropylene-based resins, and molded articles containing a thermoplastic resin composition are also described.

EFFECT: improved transparency and physical properties, as well as good heat resistance.
