Abstract:
A catalyst complex for catalysis of degradation of a polymer material is described. Said complex comprises a magnetic particulate body containing iron oxide at its surface with an average diameter of 150-450 nm, and a plurality of catalytic groups grafted onto the iron oxide surface of the magnetic particulate body, which catalytic groups comprise a bridging moiety and a catalyst entity, wherein the bridging moiety comprises a functional group for adhesion or bonding to the iron oxide surface and a linking group towards the catalyst entity, and wherein the catalyst entity comprises a positively charged aromatic heterocycle moiety, and a negatively charged moiety for balancing the positively charged aromatic moiety.

Claim (Index 9):
A method of degrading a condensation polymer material chosen from the group of polyesters, polyamides, polyamines and polyethers in a degradation reaction catalysed by a catalyst complex in solid form, wherein a carrier liquid acts as a reactant in the degradation reaction, which catalyst complex is a complex of magnetic nanoparticles and bonded thereto a plurality of catalytic groups comprising a bridging moiety and a catalyst entity, wherein the bridging moiety comprises a functional group for adhesion or bonding to the nanoparticle and a linking group towards the catalyst entity, and wherein the catalyst entity comprises a positively charged aromatic heterocycle moiety, and a negatively charged moiety for balancing the positively charged aromatic moiety, which method comprises the steps of\n providing the catalyst complex as claimed in  claim 1 ; \n providing the polymer to be degraded; \n mixing the catalyst complex, the polymer to be degraded, and the carrier liquid; \n carrying out the degradation reaction to obtain a mixture comprising monomer, oligomer, carrier liquid and catalyst complex; \n adding a polar medium, particularly water or an aqueous solution, to the mixture, to obtain a hydrophilic solution comprising monomer and a second phase comprising oligomers and catalyst complex; and \n separating the first aqueous phase from the second phase in a centrifuge.
