- the sodium content among the cycloolefin polymers Those with a small amount are those that are stored in contact with ethyl 2-cyanoacrylate and show no change in appearance, and do not affect the liquid properties of ethyl 2-cyanoacrylate.
- polyethylene and polypropylene may swell or become cloudy when they come into contact with ethyl 2-cyanoacrylate, or may adversely affect the liquid properties of ethyl 2-cyanoacrylate.
- a container is formed using cyclolefin polymer, polyethylene and polypropylene, which are relatively good plastic materials having a good resistance to 2-cyanoacrylate, and the 2-cyanoacrylate is stored in the container.
- the results of evaluating the performance of the system composition are shown in Table 2 (based on JI SK6861).
- an adhesive composition (Aron Alpha # 201: manufactured by Toagosei Co., Ltd.) was used, and 4 g was filled in a container described later.
- Example 2 The cycloolefin polymers (B) and (C) used in Example 1 were used, and for comparison, polyethylene (A) (Comparative Example 1) and polypropylene (D) (Comparative Example 2) were used.

- the use of the cycloolefin polymer enables the 2-cyanoacrylate composition to be provided as a product in a container that has significantly better long-term storage stability than conventional containers in a container. In particular, it can further expand the possibility of use as an adhesive.
- even high-purity polyethylene and polypropylene contain impurities such as metal ions derived from polymerization catalysts and polymerization terminators, and additives such as UV inhibitors.
- Cycloolefins in particular cyclopolymers obtained by polymerizing norpolene derivatives, must be high-purity and low-moisture-permeability, while they may be insufficient for use as containers As a result, it has become possible to prepare containers with significantly improved long-term storage stability compared to conventional containers.
- the low moisture permeability of the cycloolefin polymer means that the amount of water permeated into the container during long-term storage is significantly reduced, and an increase in water directly leads to quality deterioration.
- the material of the 2-cyanoacrylate-based composition is very effective.
- cycloolefin polymers especially those having a low sodium content, are excellent as container materials for 2-cyanoacrylate-based compositions is due to their excellent cyanoacrylate resistance. When it is used as a container, it does not dissolve, swell, or elute in the 2-cyanoacrylate-based composition when it comes into contact with the 2-, cyanoacrylate-based composition. This means that problems such as cracking and swelling due to erosion of the container in the liquid part are unlikely to occur. This is important to maintain the appearance of the container during long-term storage. Cycloolefin polymers can be used for both injection molding and blow molding depending on grade selection, and can be molded in various shapes. Therefore, the applicable container shape range is very wide.
- the container for a 2-cyanoacrylate composition of the present invention is particularly excellent as a container for storing a 2-cyanoacrylate adhesive widely used as an instant adhesive. It can be used effectively and widely in various industries that use agents, and in various industries that use 2-cyanoacrylate compositions.
