Abstract: Provided are a compound, an additive for synthetic resins, an additive composition for synthetic resins, a resin composition, and a molded article thereof, which can improve the properties of synthetic resins. A compound containing a monovalent group represented by general formula (1) can improve the properties of synthetic resins.




In general formula (1), X represents a divalent group, Ar1 and Ar2 each independently represent an unsubstituted or substituted phenyl group, and * represents a site bonding to another atom.

Abstract: Provided are: a novel nucleating agent capable of imparting excellent transparency to synthetic resins; a synthetic resin composition containing the same; and a molded object of the synthetic resin composition. The nucleating agent contains at least one triazine compound represented by Formula (1), wherein Ar1, Ar2 and Ar3 each independently represent an unsubstituted phenyl group or a substituted phenyl group. In Formula (1), for example, the number of substituents of the substituted phenyl group is preferably 1, and Ar1, Ar2 and Ar3 are preferably all different groups.

Abstract: Provided are: a resin composition in which a resin component has a reduced crystallinity; and a molded article of the same. The resin composition contains a polyolefin-based resin and a nucleating agent. In this resin composition, the nucleating agent is a nucleating agent that melts at a temperature 150° C. higher than the melting point of the polyolefin-based resin, or a nucleating agent that dissolves in the polyolefin-based resin at a temperature 150° C. higher than the melting point of the polyolefin-based resin; the nucleating agent, when added in an amount of 0.2 parts by mass with respect to 100 parts by mass of the polyolefin-based resin, increases the crystallization temperature of the polyolefin-based resin by at least 7° C.; and the nucleating agent is contained in an amount of 0.005 parts by mass or more but less than 0.1 parts by mass with respect to 100 parts by mass of the polyolefin-based resin.
