Abstract
Official abstract text for this publication.
The present invention relates to a copolymer containing a constitutional unit derived from acrylic acid cesium salt or acrylic acid rubidium salt and a constitutional unit derived from vinyl alcohol, a resin composition containing the copolymer, a carbon dioxide gas separation membrane which can be manufactured with the resin composition, a carbon dioxide gas separation membrane module having the separation membrane, and a carbon dioxide gas separation apparatus including at least one type of the module.
First claim
Opening claim text (preview).
The invention claimed is: 1. A resin composition, comprising: a substance reversibly reacting with a carbon dioxide gas; and a copolymer, comprising: a constitutional unit (1) expressed in a formula (1) below: where M represents cesium; and a constitutional unit (2) expressed in a formula (2) below: wherein a content of the constitutional unit (2) is from 1 mol % to 90 mol % with respect to a total content of the constitutional unit (1) and the constitutional unit (2), the substance reversibly reacting with the carbon dioxide gas is cesium carbonate or cesium hydrogencarbonate, and a content of the substance reversibly reacting with the carbon dioxide gas is within a range from 20 weight % to 90 weight % with respect to a total weight of the substance reversibly reacting with the carbon dioxide gas and the copolymer wherein the copolymer comprises a constitutional unit (3) selected from the group consisting of a constitutional unit derived from methacrylic acid alkyl ester having an alkyl group having a carbon number from 1 to 16, a constitutional unit derived from maleic acid dialkyl ester having an alkyl group having a carbon number from 1 to 16, a constitutional unit derived from fumaric acid dialkyl ester having an alkyl group having a carbon number from 1 to 16, and a constitutional unit derived from itaconic acid dialkyl ester having an alkyl group having a carbon number from 1 to 16. 2. The resin composition according to claim 1 , wherein the substance reversibly reacting with the carbon dioxide gas is cesium carbonate. 3. A carbon dioxide gas separation membrane in which a substance reversibly reacting with a carbon dioxide gas and a copolymer, comprising: a constitutional unit (1) expressed in a formula (1) below: where M represents cesium; and a constitutional unit (2) expressed in a formula (2) below: are supported by a porous membrane, wherein a content of the constitutional unit (2) is from 1 mol % to 90 mol % with respect to a total content of the constitutional unit (1) and the constitutional unit (2), the substance reversibly reacting with the carbon dioxide gas is cesium carbonate or cesium hyrdogencarbonate, and a content of the substance reversibly reacting with the carbon dioxide gas is within a range from 20 weight % to 90 weight % with respect to a total weight of the substance reversibly reacting with the carbon dioxide gas and the copolymer wherein the copolymer comprises a constitutional unit (3) selected from the group consisting of a constitutional unit derived from methacrylic acid alkyl ester having an alkyl group having a carbon number from 1 to 16, a constitutional unit derived from maleic acid dialkyl ester having an alkyl group having a carbon number from 1 to 16, a constitutional unit derived from fumaric acid dialkyl ester having an alkyl group having a carbon number from 1 to 16, and a constitutional unit derived from itaconic acid dialkyl ester having an alkyl group having a carbon number from 1 to 16. 4. A carbon dioxide gas separation membrane module, comprising the carbon dioxide gas separation membrane according to claim 3 . 5. A carbon dioxide gas separation apparatus, comprising the carbon dioxide gas separation membrane according to claim 3 .
