Abstract
The present invention relates, in part, to methods for depolymerizing a polymer, in which the method includes use of a magnetic catalyst. The magnetic catalyst can include, e.g., a ore-shell particle, such as a particle having a magnetic core and a shell including a metal-organic framework.
Claims20
A method for depolymerizing a polymer, the method comprising:
- providing the polymer and a reactant in the presence of a magnetic catalyst, wherein the magnetic catalyst comprises a magnetic core and a shell comprising a metal-organic framework;
- incubating the polymer and the magnetic catalyst at an elevated temperature, thereby forming a monomer within a reaction mixture;
- and
- applying a magnetic field, thereby separating the magnetic catalyst from the monomer and the reactant, if any.

A method for depolymerizing a polymer, the method comprising:
- providing a first polymer and a reactant in the presence of a magnetic catalyst, wherein the magnetic catalyst comprises a magnetic core and a shell comprising a metal-organic framework;
- incubating the first polymer and the magnetic catalyst at an elevated temperature, thereby forming a first monomer within a reaction mixture;
- applying a magnetic field, thereby separating the magnetic catalyst from the first monomer and the reactant, if any;
- and
- reusing the magnetic catalyst to depolymerize a second polymer, wherein the first polymer and the second polymer is the same or different.
