Abstract
Provided are: an additive composition which has an excellent extruder feed stability as a result of having an excellent powder flowability, and can impart excellent transparency and mechanical properties to molded articles; a polyolefin resin composition containing the additive composition; a method of producing a polyolefin resin composition; and a molded article of the polyolefin resin composition. The additive composition contains (A) 1-[8-propyl-2,6-bis(4-propylphenyl)tetrahydro[1,3]dioxino[5,4-d]-1,3-dioxin-4-yl]ethane-1,2-diol and (B) an aromatic phosphate metal salt represented by Formula (1) where Rto Reach independently represent an alkyl group having 1 to 6 carbon atoms; n represents a number of 1 or 2; when n is 1, Mrepresents an alkali metal; and when n is 2, Mrepresents hydroxyaluminum. In this additive composition, the mass ratio of (A) and (B), (A)/(B), is in a range of 10/90 to 90/10.
