Embodiment

[0192] Hereinafter, the present invention will be described in more detail using examples, but the present invention is not limited to them. In addition, in the following examples and comparative examples, "%" and "ppb" refer to a mass basis unless otherwise specified.

[0193] According to the following Production Examples 1 to 3, the polymer compound (E) used in the present invention was produced. In addition, in the following manufacture examples 1-3, the number average molecular weight was measured by the following molecular weight measuring method.

[0194]

[0195] The number average molecular weight (hereinafter referred to as "Mn") is measured by gel permeation chromatography (GPC) method. The measurement conditions of Mn are as follows.

[0196] Device: GPC device manufactured by JASCO Corporation

[0197] Solvent: THF

[0198] Reference material: polystyrene

[0199] Detector: Differential refractometer (RI detector)

[0200] Column stationary phase: Shodex K...

manufacture example 1-1

[0206]In detachable flask, drop into 1,4-cyclohexanedimethanol 544g, adipic acid 582g (3.98 mole), phthalic anhydride 0.7g (0.01 mole), antioxidant (tetrakis[3-(3,5 -Di-tert-butyl-4-hydroxyphenyl)propionyloxymethyl]methane, ADK STAB AO-60, manufactured by ADEKA Corporation) 0.5g, while slowly raising the temperature from 160°C to 210°C, under normal pressure Polymerization was carried out for 4 hours, followed by polymerization at 210° C. under reduced pressure for 3 hours to obtain polyester (A)-1-1. The acid value of polyester (A)-1-1 was 28, and the number average molecular weight Mn was 5,400 in terms of polystyrene.

[0207] Next, 600 g of the obtained polyester (A)-1-1, 300 g of polyethylene glycol having a number average molecular weight of 4,000 as the compound (B)-1-1 having hydroxyl groups at both ends, and an antioxidant (ADK STAB AO- 60) 0.5 g and 0.8 g of zirconium octoate were polymerized at 210° C. under reduced pressure for 7 hours to obtain a block polymer (C...

manufacture example 1-2

[0210] Put 591 g of ethylene oxide adducts of bisphenol A, 235 g (1.16 moles) of sebacic acid, 8 g (0.05 moles) of isophthalic acid, and 0.5 g of antioxidant (ADK STAB AO-60) into a detachable flask , while slowly raising the temperature from 160°C to 220°C, polymerization was carried out under normal pressure for 4 hours. Thereafter, 0.5 g of tetraisopropoxy titanate was charged and polymerized at 220° C. under reduced pressure for 5 hours to obtain polyester (A)-1-2. The acid value of polyester (A)-1-2 was 56, and the number average molecular weight Mn was 2,300 in terms of polystyrene.

[0211] Next, 300 g of the obtained polyester (A)-1-2, 200 g of polyethylene glycol having a number average molecular weight of 2,000 as the compound (B)-1-2 having hydroxyl groups at both ends, and an antioxidant (ADK STAB AO- 60) 0.5 g and 0.5 g of zirconium acetate were polymerized at 220° C. under reduced pressure for 8 hours to obtain a block polymer (C)-1-2 having a structure having c...

Abstract

Provided are: an antistatic resin composition which exhibits long-lasting and sufficient antistatic properties, and substantially no ion elution when formed into a moulded article, and which is suitable for packaging materials and containers for accommodating / transporting electrical and electronic components; and a container and a packaging material which use said antistatic resin composition. The antistatic resin composition includes, per 100 parts by mass of a synthetic resin, 3-20 parts by mass of at least one polymer compound (E), and 0.1-5 parts by mass of a salt (F) of at least one alkali metal. The polymer compound (E) is provided with a structure obtained by bonding, via ester bonds, or ester bonds and amide bonds, a diol, an aliphatic dicarboxylic acid, an aromatic dicarboxylic acid, a compound (D) having a reactive functional group, and a compound (B) which has at least one group represented by general formula (1), namely -CH2-CH2-O-, and which has hydroxyl groups provided to both terminals.

Description

technical field [0001] The present invention relates to an antistatic resin composition (hereinafter also simply referred to as "resin composition"), containers and packaging materials using the same, and in particular, to containers and packaging materials suitable for storing / transporting electrical and electronic components An antistatic resin composition which has sufficient and sustained antistatic properties and which hardly elutes ions when formed into a molded article, and containers and packaging materials using the same. Background technique [0002] Electrical and electronic equipment uses electrical components and / or electronic components such as silicon wafers, hard disks, disk substrates, glass substrates, IC chips, semiconductors, optical memory disks, color filters, hard disk head components, and CCD components (hereinafter referred to as "electrical Electronic Components"). In the assembly of these electric and electronic devices, it is necessary to convey ...
