AQUEOUS LIQUID ABSORBING RESIN, AQUEOUS LIQUID ABSORBING COMPOSITION, AND ABSORBENT BODY AND ABSORBENT ARTICLE USING SAME |
摘要 |
An absorbent resin and an absorbent composition that use a large amount of material derived from plants, have excellent absorbing capability in a compressed state due to having a favorable gel elastic modulus. An absorbent resin made by bonding (A1) an oxidized polysaccharide having a carboxyl group that may be neutralized by a neutralizing agent, and/or (A2) a crosslinked compound thereof with (B1) a poly(meth)acrylic acid where at least one of the carboxyl groups may be neutralized by a neutralizing agent, and/or (B2) a crosslinked compound thereof; or an absorbent composition made by blending (A1) and/or (A2) and (B1) and/or the (B2); wherein the weight average molecular weight of (A1) is 2,000 to 10,000,000, the acid value of (A1) is 65 to 524 mgKOH/g, and if (A1) has a carboxyl group that has been neutralized by a neutralizing agent, the acid value prior to neutralizing is 65 to 524 mgKOH/g. |

1. An aqueous liquid absorbing resin comprising (A1) an oxidized polysaccharide having a carboxyl group optionally neutralized by a neutralizing agent and/or (A2) a crosslinked product thereof and (B1) a poly(meth)acrylic acid with at least one of the carboxyl groups thereof optionally being neutralized by a neutralizing agent and/or (B2) a crosslinked product thereof, the (A1) and/or the (A2) being bonded with the (B1) and/or the (B2), wherein the weight average molecular weight of the (A1) is 2,000 to 10,000,000, the acid value of the (A1) is 65 to 524 mgKOH/g when the (A1) has no carboxyl groups neutralized by a neutralizing agent, and the acid value of the (A1) prior to its neutralization is 65 to 524 mgKOH/g when the (A1) has a carboxyl group neutralized by a neutralizing agent. |
