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.

Abstract: Provided are: a nucleating agent composition capable of imparting excellent mechanical properties to a molded article containing a polyolefin-based resin; a resin composition containing the nucleating agent composition; the molded article having excellent mechanical properties; and a method for manufacturing the resin composition. The nucleating agent composition is characterized by containing at least one type of a nucleating agent for a polyolefin-based resin, wherein a β crystal fraction ranges from 0.2% to 71% as calculated by the following method. Through the use of a sample sampled from the pellets of the resin composition containing the nucleating agent composition, differential scanning calorimetry is performed according to a predetermined program to find a DSC curve, Q=f(θ), with the horizontal axis being temperature θ(° C.) and the vertical axis being heat flow rate Q(mW), and a baseline, g(θ), thereby obtaining a baseline-corrected DSC curve, Q′=h(θ)=f(θ)−g(θ). Subsequently, according to a predetermined procedure, a line area St and a β crystal area Sβ are found, thereby calculating the β crystal fraction (%).
