DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of an interior material having an odor / hazardous gas adsorption function according to the present invention will be described.

(First Example) In this example, an interior member 1 formed in a sheet, plate or other appropriate shape is used as a base, and a functional group having a capability of adsorbing a polar substance is formed on the base.
A macromonomer containing a hydrophilic group and a cationic dissociating group and / or an anionic dissociating group is bound by radiation graft polymerization.

As used herein, the interior member 1 refers to a member serving as an interior material used for, for example, curtains, tapestries, light umbrellas, sofa covers, tablecloths, ornaments, trash containers, and the like. There is no particular limitation, and any material can be used as long as it can bind to the macromonomer.

Using the interior member 1 as a base,
The macromonomer bonded by radiation graft polymerization refers to a polymer having a degree of polymerization intermediate between the degree of polymerization of the oligomer and the degree of polymerization of the polymer.

The hydrophilic group contained in the macromonomer refers to a group (nonion) which has an affinity for water and does not dissociate ions when contacted with water. Such a hydrophilic group can supplement water present in the air, and the captured water molecules are adsorbed on the surface of the substrate to form a water layer,
It will dissolve polar substances and dissociate ionic substances. Such hydrophilic groups include, for example, hydroxyl, hydroxyalkyl and pyrrolidonyl groups.

The cationic dissociation group means an ion exchange group whose counter ion is a cation, and is an acid group. The cationic dissociating group has a capability of adsorbing a polar substance, is capable of releasing a hydrogen ion and neutralizing with a basic substance,
As a result, the basic substance is removed. Such cationic dissociating groups include, for example, carboxyl groups,
There are a sulfone group, a phosphate group, a sulfoethyl group, a phosphomethyl group and a carbomethyl group.

The anionic dissociating group refers to an ion exchange group whose counter ion is an anion, which has the ability to adsorb a polar substance and is capable of neutralizing with an acidic substance. Material will be removed. Such anionic dissociating groups include, for example, primary to tertiary amino groups and
There are quaternary ammonium groups.

By the way, there are various harmful gas components and odor components, and they are generally combined. The adsorption of these gas components by the above-mentioned ion exchange group is chemical adsorption, and unlike activated carbon of physical adsorption, once adsorbed components can be reactivated by changes in operating conditions such as temperature / pressure changes and start / stop. However, it is difficult to remove any gas other than the acidic gas and the basic gas. For example, neutral harmful gas components such as acetaldehyde and formaldehyde cannot be removed simply by contacting the ion-exchange group with a substrate supported by the binding of a macromonomer. In this case, a substance having an amino group or the like is further supported on the substrate. This makes it possible to remove not only acidic gas and basic gas but also neutral harmful gas components.

In this embodiment, the interior member 1 is used.
As a macromonomer bound to a single macromonomer containing a specific functional group,
Also included are those in which a plurality of macromonomers containing different types of functional groups are bonded.
