A propylene resin composition comprising: The propylene polymer (I) is a propylene homopolymer (I-1) or a propylene copolymer (I-2). The propylene copolymer (I-2): a copolymer comprising a structural unit derived from propylene and a structural unit derived from at least one olefin selected from the group consisting of ethylene and &#x3b1;-olefins having 4 to 12 carbon atoms, where

Propylene resin composition and shaped body comprising same

A propylene-based polymer composition having good thermal stability and yielding a molded product have a favorable appearance is provided. The composition contains a propylene-based polymer (A) selected from a propylene homopolymer (A-1) and a heterophasic propylene-based polymer (A-2), carbon black (D), and optionally ethylene-&#x3b1;-olefin copolymer (B). The content of (D) is 0.001 to 1.7 parts by weight with respect to 100 parts by weight of (A). The primary particle size of the carbon black is 15 nm to 39 nm, and x defined by the following formula (1) is 1 to 430.&#x2003;&#x2003;(1)In formula (1), a is the concentration (unit: atom %) of oxygen double-bonded to carbon on the surface of the carbon black, and S is the nitrogen adsorption specific surface area (unit: m/g) of the carbon black.

Propylene-based polymer composition and injection-molded product made thereof

The present invention provides an agrochemically active microbial formulation comprising a combination of an agrochemically active microbe with a specified ester compound and a surfactant, the formulation exhibiting a stable pest controlling effect with no harmful effect on a plant and having highly stable viability of the agrochemically active microbe.

Agrochemically active microbial formulation

Provided are a polypropylene resin composition which produces only a little mold staining at the time of molding, which is excellent in the stability against light and the molding processability, which has good balance between high rigidity and impact resistance, and which can give a molded article excellent in flow mark appearance and weld appearance when being processed into a molded article, and a molded article produced therefrom. The polypropylene resin composition of the present invention contains 99 to 60 parts by weight of propylene-based polymer (A), 1 to 40 parts by weight of inorganic filler (B) having an average particle diameter of 0.01 to 100 &#x3bc;m, and 0.05 to 5 parts by weight, per 100 parts by weight of the resin composition (I), of an hindered amine-type light stabilizer (C) which satisfies the specified requirements (a), (b) and (c), provided that the combined amount of the propylene-based polymer (A) and the inorganic filler (B) is 100 parts by weight.
