Abstract

The invention discloses a catalytic supported polymer. The structural formula is any one of a formula (I) or a formula (II). In the formulas, A is a urea or thiourea group, B is onium salt with positive charges, M is a comonomer, and X is a corresponding negative charge balance ion; and m represents the number of A and is any integer between 1 and 100000, and n represents the number of onium salt groups and is any integer between 1 and 100000. The invention also discloses a preparation method of the catalytic supported polymer, and application in catalysis of polymerization of one or more cyclic monomer bodies for obtaining amacromolecular polymer or a reaction of one or more cyclic monomers with carbon dioxide, carbon disulfide, carbon oxysulfide and carbon monoxide to obtain small molecular compounds and macromolecular polymers of cyclic carbonate cyclic lactone, and cyclic thiocarbonate. The catalytic supported polymer has relatively high catalytic activity and selectivity when applied to catalytic preparation of organic micromolecule and macromolecular polymers.

Description

technical field [0001] The invention relates to a supported cross-linked polymer with multiple catalytic properties and a preparation method thereof. The supported cross-linked polymer prepared by the method can be used as a heterogeneous catalyst to prepare organic small molecule fine chemicals or macromolecular polymerization material. Background technique [0002] Organic catalysts have important application potential in the preparation of organic fine chemicals. Such as: catalytic epoxidation of substrates with carbon dioxide (CO 2 ) to obtain cyclic carbonates and the like. Cyclic carbonates are an important class of heterocyclic compounds, which are widely used in polar aprotic solvents, lithium-ion batteries, organic synthesis intermediates, and pharmaceutical and fine chemical industries. In the past decades, many efficient catalysts for cyclic carbonate synthesis including salen-metal complexes, quaternary ammonium / phosphonium salts, ionic liquids, metal-organic ...
