METHODS OF CHEMICAL DECONSTRUCTION AND UPCYCLING OF WASTE POLYMERS INTO VERSATILE VITRIMER ADHESIVES

원문 (중국어)

A method of deconstructing and upcycling used polymeric material containing carbonyl groups in the backbone of the polymer comprising: (i) reacting the polymeric material with a polyamine molecule under conditions that result in covalent attachment of the polyamine molecule with the polymer in the polymeric material to produce an aminated monomer, wherein the aminated monomer contains a multiplicity of free unreacted amino groups from the polyamine molecule, and the polyamine molecule contains at least three amino groups; and (ii) reacting the aminated monomer with a poly(acylacetate) compound under conditions that result in reaction between a portion of the free unreacted amino groups in the aminated monomer and carbonyl groups in the bis(acylacetate) compound of Formula (3) to result in a crosslinked polymer containing vinylogous urethane covalent linkages and free unreacted amino groups. A method for bonding surfaces together by use of the above described crosslinked polymer is also disclosed herein.
