- Anion exchange composition used for preparation of resin kneaded body B_Z_1 1 In the same manner as in Example 74 except that anion exchange composition 2-4 was used instead of 5, resin kneaded body B—Z—12 was produced. A pulverized sample was prepared by pulverizing in the same manner.
- Anion exchange composition used for production of resin kneaded body B_Z_1 1 In the same manner as in Example 74 except that anion exchange composition 2-5 was used instead of 5, resin kneaded body B_Z_13 was made. A pulverized sample was prepared by pulverizing in the same manner.
- Anion exchange composition used for preparation of resin kneaded body B_Z_1 1 In the same manner as in Example 74 except that anion exchange composition 2-1 was used instead of 5, resin kneaded body B_Z_15 was made. A pulverized sample was prepared by pulverizing in the same manner.
- a comparative resin kneaded body B was prepared in the same manner as in Example 74 except that the anion exchange composition 115 was not used. This was similarly pulverized to prepare a pulverized sample. The ground sample was used for a chloride ion elution test.
- Example 81 Resin kneaded body B—Z— 8 40 6.8
- Example 82 Resin kneaded body B—Z— 9 41 6.7
- Example 83 Resin kneaded body B—Z—10 20 6.8
- Example 84 Resin kneaded body B—Z—11 20 6.8
- Example 85 Resin kneaded body B—Z—12 41 6. 8
- Example 86 Resin kneaded body B—Z—13 42 6.7
- Example 87 Resin kneaded body B—Z— 14 40 6.8
- Example 88 Resin kneaded body BZ— 15 18 6.9 Comparative example 18 Comparative resin kneaded body B—H— 1 40 6.
- the anion exchanger of the present invention has low hygroscopicity and / or excellent heat resistance, and has a high anion exchange rate even near neutrality. Even if the anion exchanger of the present invention is added to the resin, there is an effect of suppressing the elution of anions from now on. From this, the anion exchanger of the present invention can be used for various applications such as sealing, covering, and insulating of electronic parts or electric parts with high reliability in a wide range.
- the anion exchanger of the present invention can also be used as a stabilizer for a resin such as vinyl chloride and an antifungal agent.
