Abstract:
A method of degrading a polymer into oligomers and/or monomers in a solvent, using a catalyst, and a functionalized magnetic particle comprising a catalyst being capable of degrading the polymer into oligomers and/or monomers. The present method and particle provide a high selectivity and a high conversion ratio.

Claim (Index 18):
Method of degrading a homo- or copolymer into oligomers, trimers, dimers and/or monomers, comprising the steps of:\n providing the polymer in a suitable solvent, the polymer being in solid form, wherein the polymer is one or more of a polyester, a polyamide, a polycondensate and a polyether, wherein the solvent is a mono- or di-alcohol, adjusting temperature and pressure to reaction conditions, providing a catalyst complex being capable of degrading the polymer into oligomers and/or monomers, wherein the polymer, solvent and catalyst complex constitute a dispersion, wherein said catalyst complex comprising functionalized magnetic particles, wherein the functionalization comprises a bridging moiety and a catalyst entity bonded to the bridging moiety, said catalyst entity comprising an aromatic heterocyclic moiety, degrading the polymer by means of glycolysis over a period sufficient to degrade a significant portion thereof into oligomers, trimers, dimers and monomers, in which degradation of the polymer, the solvent functions as a reactant, recovering the catalyst complex, wherein a second solvent is provided as a washing agent, said second solvent being water, wherein the catalyst complex, oligomers trimers and dimers form a separate phase, and wherein monomers and the mono- or di-alcoholic solvent dissolve in the water, and retrieving monomers from the second solvent by means of crystallisation.
