Abstract
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.
