Title:
METHOD FOR PREPARING POLYTHIOIMIDATE BASED ON MULTI-COMPONENT POLYMERIZATION OF ALKYNE, SULFONYL AZIDE AND THIOL
Document Type and Number:
WIPO Patent Application WO/2024/011744
Kind Code:
A1
Abstract:
The present application relates to a method for preparing polythioimidate on the basis of multi-component polymerization of alkyne, sulfonyl azide and thiol. The method comprises the following steps: performing a multi-component polymerization reaction on a diyne monomer, a dithiol monomer, sulfonyl azide and alkali in a reaction solvent under the action of a monovalent copper catalyst in a protective atmosphere to obtain polythioimidate. The method is simple to operate, mild in reaction condition and high in atom economy; only nitrogen byproducts are generated; the group tolerance is strong; a plurality of functional groups can be introduced into the monomers; the weight-average molecular weight of polythioimidate ranges from 4000 g/mol to 13000 g/mol; and the polythioimidate has excellent selective adsorption properties on heavy metal nickel ions (Ni2+), and has a unique application value in the aspect of enrichment of heavy metal ions.
