Problems solved by technology

[0006] In addition, polyolefin-based resins have excellent electrical insulation properties as described above, but have the problem of easily generating or accumulating static electricity, causing dust and the like to easily adhere to the surface and be polluted, which often reduces the commercial value. In addition, there is a problem that the molding cycle is long because the crystallization rate after molding is slow, and the crystallization proceeds after heating molding to generate large crystals inside the molded body, thereby reducing transparency and strength.

Embodiment 1

[0414] Hereinafter, the present invention will be specifically described by way of examples.

manufacture example 1-1

[0416] (Manufacture of polymer compound (E)-1-1)

[0417] 420 g of 1,4-cyclohexanedimethanol as diol, 485 g of adipic acid as aliphatic dicarboxylic acid, 0.5 g of isophthalic acid as aromatic dicarboxylic acid, antioxidant (Tetrakis[3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionyloxymethyl]methane, trade name "ADK STAB AO-60" manufactured by ADEKA Corporation) 0.5 g, zirconium acetate 0.5 g, and polymerized under normal pressure for 4 hours while slowly raising the temperature from 160°C to 200°C. Then, polymerization was carried out at 200° C. under reduced pressure for 3 hours to obtain polyester (A)-1-1. The acid value of polyester (A)-1-1 was 56, and the number average molecular weight Mn was 3,200 in terms of polystyrene.

[0418] Next, 600 g of the obtained polyester (A)-1-1, 400 g of polyethylene glycol ((B)-1-1) having a number average molecular weight of 2,000 as the aforementioned compound (B), and an antioxidant (ADK STAB AO- 60) 0.5 g and 0.5 g of zirconium aceta...

manufacture example 1-2

[0421] (Manufacture of polymer compound (E)-1-2)

[0422] 490 g of 1,4-cyclohexanedimethanol as a diol, 524 g of adipic acid as an aliphatic dicarboxylic acid, 0.5 g of phthalic anhydride as an aromatic dicarboxylic acid, and Oxidant (ADK STAB AO-60) 0.5g, polymerized at normal pressure for 5 hours while slowly raising the temperature from 160°C to 210°C, then polymerized at 210°C under reduced pressure for 3 hours to obtain polyester (A) -1-2. The acid value of polyester (A)-1-2 was 28, and the number average molecular weight Mn was 5,400 in terms of polystyrene.

[0423] 500 g of the obtained polyester (A)-1-2, 250 g of polyethylene glycol ((B)-1-2) having a number average molecular weight of 4,000 as the aforementioned compound (B), and an antioxidant (ADK STAB AO-60) were charged. 0.5 g and 0.7 g of zirconium octoate were polymerized at 210° C. under reduced pressure for 7 hours to obtain a block polymer (C)-1-2. The acid value of the block polymer (C)-1-2 was 9, and th...

Abstract

Provided are a resin additive composition whereby excellent antistatic effects can be imparted using a small added amount thereof, and an antistatic thermoplastic resin composition. A resin additive composition containing 0.001-50 parts by mass of two or more species selected from metal salts of aromatic phosphate esters represented by general formula (3) or (4) with respect to 100 parts by mass of a polymer compound (E). The polymer compound (E) has a structure obtained by bonding, via ester bonds, of a diol, an aliphatic dicarboxylic acid, an aromatic dicarboxylic acid, a compound (B) having one or more groups represented by general formula (1) and having hydroxyl groups at both terminal ends thereof, and an epoxy compound (D) having two or more epoxy groups.

Description

technical field [0001] The present invention relates to a resin additive composition and an antistatic thermoplastic resin composition (hereinafter also referred to as "additive composition", "resin composition"), in detail, the present invention relates to a resin additive composition and antistatic A thermoplastic resin composition, the resin additive composition can suppress the decrease in physical properties caused by the addition of an antistatic agent, and can impart excellent antistatic properties to a thermoplastic resin, and the antistatic thermoplastic resin composition can provide A molded product with a short molding cycle, transparency, strength, and durability, and excellent antistatic properties. Background technique [0002] Among thermoplastic resins, polyolefin-based resins are excellent in molding processability, heat resistance, and mechanical properties, as well as having low specific gravity, so they are widely used in various molded products such as f...
