The present invention is in the field of an improved reusable capture complex and a method of releasable capturing an additive present in a polymer material. The capture complex comprises a catalyst entity, a magnetic nanoparticle, and a bridging moiety solely between the catalyst entity and the magnetic nanoparticle The present use and method provide a high reduction of free additive of a polymer material.

Reusable capture complex

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.

Catalyst complex and method of degradation of a polymer material

The present invention is in the field of an improved separation process for mixed polymers, typically provided in a waste stream, comprising a polyamide (PA) and a polyethylene terephthalate (PET). The process comprises providing a composition having a density of 50-500 gr/dm3, adding an alcohol to the composition heating the mixture to a temperature above 150&#xb0; C., cooling by adding hot water, filtering with a first filter, filtering with a second filter to recover the polyamide, and recovering the polyester for further processing for depolymerization.

PA/PET separation process

An improved reusable capture complex and a method of capturing an additive releasable from a polymer material are disclosed. The capture complex includes a catalyst entity, a magnetic nanoparticle, and a bridging moiety between the catalyst entity and the magnetic nanoparticle. The method provides a high reduction of free additive of a polymer material.
