COMPOSITION OF RESIN ADDITIVE, COMPOSITION OF THERMOPLASTIC RESIN AND MOLDED PRODUCT FROM IT Russian patent published in 2022 - IPC C08K5/527 C08K5/98 C08L101/00 C08L23/00 

FIELD: chemistry.

SUBSTANCE: group of inventions relates to a composition of thermoplastic resin and a molded product from it. The composition of thermoplastic resin for the manufacture of molded products contains a composition of a resin additive containing phosphoric acid ether (A) represented by the following general formula (1):

,

where in the formula (1), each of R¹-R⁴ is independently a branched alkyl group having 1-9 carbon atoms, and R⁵ is an alkylidene group having 1-4 carbon atoms and sodium salt of fatty acid (B) represented by the following general formula (2):

,

where in the formula (2), R⁶ is a group introduced from aliphatic organic acid having 7-30 carbon atoms. In this case, the mass ratio (B)/(A) = 0.55-2.0, and phosphoric acid ether (A) represented by the general formula (1) is 0.001-10 mass parts per 100 mass parts of thermoplastic resin. The composition of thermoplastic resin additionally contains 1-80 mass parts of thermoplastic elastomer (C) and 1-80 mass parts of filler (D). Molded products containing a composition of thermoplastic resin are also described.

EFFECT: improvement of the efficiency of a nucleating agent while increasing the impact resistance of resin and suppressing yellowing.
