Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A polyolefin resin composition, comprising a nucleating agent in an amount of 0.001 to 10 parts by mass with respect to 100 parts by mass of a polyolefin resin, the nucleating agent, comprising: a compound represented by the following Formula (1): wherein in Formula (1), R 1 to R 4 each independently represent a hydrogen atom or a linear or branched alkyl group having 1 to 9 carbon atoms; R 5 represents an alkanediyl group having 1 to 4 carbon atoms; and M represents a sodium atom, and a compound represented by the following Formula (1′): wherein in Formula (1′), R 1 to R 4 each independently represent a hydrogen atom or a linear or branched alkyl group having 1 to 9 carbon atoms; R 5 represents an alkanediyl group having 1 to 4 carbon atoms; and M represents a hydrogen atom, wherein a mass ratio of phosphorus atoms and sodium atoms in the nucleating agent, P/Na, is in a range of 1.350 to 1.500. 2. The polyolefin resin composition according to claim 1 , wherein the mass ratio of phosphorus atoms and sodium atoms in the nucleating agent, P/Na, is in a range of 1.350 to 1.450. 3. The polyolefin resin composition according to claim 1 , wherein the polyolefin resin is at least one selected from the group consisting of a polypropylene and an ethylene-propylene block or random copolymer. 4. A molded article obtained by molding the polyolefin resin composition according to claim 1 .
