Polyolefin-based resin composition, method for producing same, and use of said composition

Abstract

The present invention provides: a polyolefin-based resin composition having high crystallinity (a high crystallization temperature) and excellent mechanical properties (especially impact strength); and a method for producing the same. The present invention also provides: a crystal nucleating agent composition for polyolefin-based resins, said composition being used for the production of the polyolefin-based resin composition; and a method for producing this crystal nucleating agent composition. Furthermore, the present invention provides a polyolefin-based resin molded body containing the polyolefin-based resin composition. The present invention relates to: a polyolefin-based resin composition that contains a compound represented by general formula (1), an antistatic agent (Z) containing a block polymer (A) having a block of a polyolefin (a2) and a block of a polyether (b1) as constituent units, and a polyolefin-based resin; a crystal nucleating agent composition for a polyolefin-based resin; methods for producing the polyolefin-based resin composition and the crystal nucleating agent composition; and a polyolefin-based resin molded body. [In the formula, R1 is a C1-4 alkyl group; R1 is bonded to the 3- or 4-position carbon on the cyclohexane ring; M1 is calcium, zinc, hydroxyaluminum, sodium, or lithium; when M1 is calcium, zinc, or hydroxyaluminum, a is 2 and b is 1; and when M1 is sodium or lithium, a is 1 and b is 2.]
