specific example

[0267] When the effect of improving transparency is important, the amido compound represented by the general formula (1) is preferred, wherein R 1 A residue obtained by removing all carboxyl groups from 1,2,3-propanetricarboxylic acid or 1,3,5-benzenetricarboxylic acid. The specific examples are as follows:

[0268] 1,2,3-Propanetricarboxylic acid tricyclohexylamide;

[0269] 1,2,3-propanetricarboxylic acid tris(2-methylcyclohexylamide);

[0270] 1,2,3-propanetricarboxylic acid tris(3-methylcyclohexylamide);

[0271] 1,2,3-propanetricarboxylic acid tris(4-methylcyclohexylamide);

[0272] 1,3,5-Benzenetricarboxylic acid tricyclohexylamide;

[0273] 1,3,5-Benzenetricarboxylic acid tris(2-methylcyclohexylamide), etc.

[0274] The above amide-based compounds may be used alone or in appropriate combination of two or more.

[0275] The crystal form of the amido compound of the present invention is not limited as long as the effect of the present invention can be achieved; any ...

Embodiment

[0335] The present invention is described in detail with reference to the following Examples and Comparative Examples, but the Examples and Comparative Examples are not intended to limit the present invention.

[0336] The pH value and particle size of the inorganic compound used according to the present invention are measured by the methods described in the following items (1) and (2), respectively. The crystallinity, rigidity, heat resistance and transparency of the polyolefin-based resin molded body were evaluated by the methods described in the following items (3) to (6), respectively.

[0337] (1) pH value

[0338] 50 ml of a 50 v / v % ethanol aqueous solution was put into a 100 ml Erlenmeyer flask, and then 1 g of an inorganic compound was added thereto. The mixture was stirred with a magnetic stirrer in a constant temperature bath at 25° C. to disperse the inorganic compound. At exactly 10 minutes after the addition of the inorganic compound, the pH of the stirred disp...

preparation example 1

[0352] 9.7 g (0.055 mol) of 1,2,3-propanetricarboxylic acid and 100 g of N-methyl-2-pyrrolidone were put into a 500 ml four-necked flask equipped with a stirrer, thermometer, cooling tube and gas inlet. The mixture was stirred at room temperature under a nitrogen atmosphere until the 1,2,3-propanetricarboxylic acid was completely dissolved.

[0353] Next, 20.5 g (0.1815 mol) of 2-methylcyclohexylamine (trans isomer: cis isomer = 74.3: 25.7; GLC area %), 56.3 g (0.1815 mol) of triphenyl phosphite, 14.4 g (0.1815 mol) of pyridine, and 50 g of N-methyl-2-pyrrolidone, and the mixture was reacted at 100° C. for 4 hours while stirring in a nitrogen atmosphere. After cooling, the reaction solution was slowly poured into a mixture of 500 ml of isopropanol and 500 ml of water, and the resulting mixture was stirred at about 40° C. for 1 hour. Then, the white precipitate thus formed was filtered off. The resulting white solid was washed twice with 500 ml of isopropanol at about 40°C, a...

Abstract

A polyolefin resin composition which comprises: 100 parts by weight of a polyolefin resin; 0.01-1 part by weight of (A) a specific amide compound; and 0.005-1 part by weight of (B) at least one inorganic compound selected from the group consisting of hydrotalcites, burned hydrotalcites, talc, alkali aluminum composite hydroxides, magnesium hydroxide, magnesium oxide, calcium carbonate, and calcium oxide. Also provided is a polyolefin resin molding excellent in crystallinity, rigidity, and transparency.

Description

technical field [0001] The present invention relates to a novel polyolefin-based resin composition and a preparation method thereof; a polyolefin-based resin molded body obtained by molding the polyolefin-based resin composition; a method for improving the transparency of the polyolefin-based resin; A method for improving rigidity of polyolefin-based resin; and a nucleating agent composition for polyolefin-based resin. Background technique [0002] Polyolefin-based resins are used in various fields such as materials for film forming, sheet forming, blow molding, injection molding, etc. due to their excellent formability, mechanical properties, electrical properties, and the like. However, polyolefin-based resins having such excellent physical properties have problems that transparency, crystallinity and rigidity are generally low. In order to overcome such problems, a technique of using an amide compound or the like as a nucleating agent composition has been proposed (Paten...
