Particles of a transition metal are used as a catalyst for depolymerisation of condensation polymers in alcohol. In the method of catalysed depolymerisation of a condensation polymer in a solid form into monomers and/or oligomers, transition metal particles; are mixed with the condensation polymer in alcohol to obtain a reaction mixture. This reaction mixture is processed to disperse the condensation polymer into the alcohol and decompose it, wherein the transition metal particles act as a catalyst and the alcohol is a reagent. The catalyst is particularly supplied as a catalyst composition of transition metal particles in an alcoholic liquid. The transition metal particles are typically non-porous and may have an oxide surface.

Decomposition of condensation polymers

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.
