    摘要: Provided are: a nucleating agent capable of simultaneously improving the thermal stability and the transparency of a polyolefin resin; a polyolefin-based resin composition containing the same; and a molded article of the composition. The nucleating agent contains a compound represented by Formula (1) below where R1 to R4 each independently represent a hydrogen atom or a linear or branched alkyl group having 1 to 9 carbon atoms; R5 represents an alkanediyl group having 1 to 4 carbon atoms; and M represents a hydrogen atom or a sodium atom. In this nucleating agent, the mass ratio of phosphorus atoms and sodium atoms, P/Na, is in a range of 1.200 to 1.500.

    摘要: Provided are: a composition that can impart a thermoplastic resin with excellent transparency and physical properties; a thermoplastic resin composition containing the same; and a molded article thereof. The composition contains: (A) a cyclic organophosphate aluminum salt represented by Formula (1) below, wherein R1 to R4 each independently represent a hydrogen atom or a linear or branched alkyl group having 1 to 9 carbon atoms and R5 represents an alkylidene group having 1 to 4 carbon atoms; (B) a sodium carboxylate; and (C) a fatty acid metal salt represented by Formula (2) below, wherein R6 represents a group which is introduced to an aliphatic organic acid having 10 to 30 carbon atoms and M1 represents lithium or potassium, wherein the following ranges are satisfied in terms of molar ratio:(C)/(B)=0.30 to 5.00, and (A)/{(B)+(C)}=0.15 to 0.70.
