Title:
CROSSLINKED STRUCTURE, METAL SCAVENGING MATERIAL INCLUDING SAID CROSSLINKED STRUCTURE, METHOD FOR RECOVERING METAL USING SAID METAL SCAVENGING MATERIAL, AND METHOD FOR PRODUCING SAID CROSSLINKED STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2023/048124
Kind Code:
A1
Abstract:
Provided is a water-insoluble crosslinked structure having an exceptional metal scavenging effect. In the crosslinked structure according to the present disclosure, one linear polymer having a plurality of pendant groups represented by formula (a) and another linear polymer having a plurality of pendant groups represented by formula (a) are crosslinked by binding some of the pendant groups of the one linear polymer and some of the pendant groups of the other linear polymer to one another using a cross-linking agent. In the formula, ring Z represents a heterocycle including a nitrogen atom as a heteroatom, and R1 represents a single bond or a C1-10 alkylene group. Q+ represents a counter cation.
