Embodiment 1

[0092] Using an extruder, 5 parts by weight of Sample 1 synthesized in Example 1 and 95 parts by weight of ABS were melt-kneaded to obtain a polymer composition. The concentration of K ions present in the form of acrylate in the polymer composition was 0.07 mol / kg.

[0093] This composition was formed into a sheet by injection molding, and the surface intrinsic resistivity of the obtained sheet was measured. The results are shown in Table 2 below.

Embodiment 2~10

[0095] In Example 1, the saponified polymer (A) was changed to the substance indicated by the saponified product serial number shown in the following Table 2, and the compounding amount was changed to the ratio shown in the following Table 2 at the same time as in Example 1 conduct. The results are shown in Table 2 below.

Embodiment 11

[0099] In Example 1, the saponified polymer (A) was replaced with the substance indicated by the saponified product serial number shown in Table 3 below, and the compounding amount was changed to the ratio shown in Table 3 below, and the polymer was obtained by dry mixing For the composition, an injection-molded sheet was produced in the same manner as in Example 1, and the surface specific resistivity of the obtained sheet was measured. The results are shown in Table 3 below.

Abstract

Disclosed is a composition containing a styrene resin. The composition comprises: not less than 2 parts by mass and less than 100 parts by mass of a saponified polymer (A) produced by saponifying a copolymer of ethylene and an unsaturated carboxylic acid ester with potassium and having a potassium ion concentration of 0.1 to 5.8 mol / kg; and more than 0 part by mass and not more than 98 parts by mass of a styrene resin (B), wherein the composition has a potassium ion concentration of 0.002 to 5.8 mol / kg.

Description

technical field [0001] The present invention relates to a composition containing a styrene resin and an alkali-saponified product of an ethylene-unsaturated carboxylic acid ester copolymer having specific properties, and a molded article. Background technique [0002] With the popularization of electric factors in consumer materials and industrial products composed of various plastics, synthetic fibers, synthetic papers, etc., the demand for plastics with antistatic properties and further antistatic properties such as antistatic properties has increased dramatically. [0003] Among the substances used as the above-mentioned antistatic plastics are ionomer resins. [0004] Ionomers are known to partially neutralize copolymers of ethylene and unsaturated carboxylic acids with metals, and alkali metals, especially metals containing K, Rb, and Cs ions, exhibit excellent ion conductivity due to their ionic conductivity. Antistatic properties. In addition, it is known that even ...
