Definitions
- the present invention relates to a container and a blow-molded article, and more particularly, is suitable for applications requiring low elution, such as a storage and storage container for a chemical solution for semiconductor production. And a blow molded article.
- High-purity chemicals such as chemicals for semiconductor manufacturing, do not want to be contaminated with impurities and the like. * A certain level of purity is required for storage and transportation of these chemicals. To store and transport these high-purity chemicals Conventionally, materials such as polyethylene and polypropylene have been used as containers.
- polyethylene, polypropylene, etc. elute the metal elements contained in trace amounts in the resin together with the low molecular weight organic components.
- impurities may be mixed into the chemical solution stored and stored in the container, and it is not satisfactory enough.
- cyclic olefin-based thermoplastic resins such as norbornane-based polymers have excellent properties such as low elution and chemical resistance, so they can be used for medical and food containers. Proposed :
- Japanese Patent Application Laid-Open No. Hei 4-272653 discloses an example in which a 200 m2 two-layer blow container is formed using a norbornane-based ring-opening polymer and a polycarbonate.
- Japanese Patent Application Laid-Open No. 10-1577-119 discloses examples in which a container having a size of about 200 m1 is formed using a thermoplastic norbornane-based resin. Have been.
- containers for semiconductor processing liquids, etc. are mainly used in capacities of several tens of liters, and should be as light as possible for transportation. Are required, so that they have a large capacity, are thin, and have sufficient mechanical strength. There is a need for materials that are suitable for molding small containers. Disclosure of the invention
- the present invention has been made in view of the above circumstances, and has a container and a mouth which are excellent in low elution property and which can obtain sufficient strength even when the thickness of the container body is reduced when molding a large container.
- the purpose is to provide one compact.
- the layer (I) containing a cyclic olefin-based thermoplastic resin and the layer (II) containing a resin other than the cyclic olefin-based thermoplastic resin are reduced in number.
- the cyclic olefin-based thermoplastic resin has a repeating unit (A) having an alicyclic structure of 30% by weight or more, and 10 weight in a repeating unit (A) having an alicyclic structure. /.
- a container characterized by the above (Ai) having an alicyclic structure other than the norbornane structure BRIEF DESCRIPTION OF THE FIGURES
- FIG. 1 shows an embodiment of the container according to the present invention.
- A is a longitudinal sectional view of the container
- B is an enlarged view of the intersection of (A)
- C is the bottom of (A).
- D is an enlarged view of the main part of (A).
- Fig. 2 is a sectional view showing a mold for multilayer blow molding.
- FIG. 3 is a longitudinal sectional view showing another embodiment of the container according to the present invention.
- the container according to the present invention comprises at least a layer (I) containing a cyclic olefin-based thermoplastic resin and a layer (II) containing a resin other than the cyclic olefin-based thermoplastic resin.
- the cyclic olefin-based thermoplastic resin contains 30% by weight or more of the repeating unit (A) having an alicyclic structure, and A repeating unit having a cyclic structure (A) in which at least 10% by weight has an alicyclic structure other than the norbornane structure (A-i) Is:
- the cyclic olefin-based thermoplastic resin used in the present invention has an alicyclic structure in a main chain and / or a side chain, and has a main chain having an alicyclic structure in view of mechanical strength and heat resistance. Those containing an alicyclic structure are preferred.
- Examples of the alicyclic structure of the polymer include a cycloalkane structure (such as a norbornane ring structure, a cyclohexane structure, and a cyclopentane structure), and a cycloalkane structure (such as a norbornane ring structure).
- Examples include a cyclohexene structure and a cyclopentene structure, but a cycloalkane structure is preferred from the viewpoint of mechanical strength and thermal stability.
- the number of carbon atoms constituting the alicyclic structure is not particularly limited, but is usually in a range of 4 to 30, preferably 5 to 20 and more preferably 5 to 15. In some cases, the properties of mechanical strength, heat resistance, and moldability are highly balanced, which is preferable.
- the proportion of the repeating unit having an alicyclic structure in the cyclic olefin-based thermoplastic resin used in the present invention may be appropriately selected according to the purpose of use. 0% to 100% by weight. /. Preferably 50% by weight to 100% by weight 0 /. And more preferably from 70% by weight to 100% by weight. 3
- the proportion of the repeating unit having an alicyclic structure constituting the alicyclic structure-containing polymer resin is excessively small. Inferior in heat resistance and within the above range, mechanical strength, heat resistance, etc. are highly balanced.
- the proportion of the repeating unit having an alicyclic structure other than the norbornane ring in the repeating unit having an alicyclic structure is preferably 10% by weight. /. Above, more preferably 30 weight. /. As mentioned above, the weight is more preferably 50 weight. /. That is all.
- a cyclic unit having an alicyclic structure in a cyclic olefin-based thermoplastic resin The rest other than the place is not particularly limited and is appropriately selected according to the purpose of use .:
