摘要： The present invention relates to a method for depolymerising oxygenated polymer materials, in particular by nucleophilic catalysis and to the use of said method in the recycling of plastic materials and the preparation of aromatic and aliphatic compounds that can be used as fuel, synthesis intermediates, raw materials in the construction sector, and in the petrochemical, electrical, electronic, textile, aeronautical, pharmaceutical, cosmetic and agrochemical industry. The present invention also relates to a method for manufacturing fuels, electronic components, plastic polymers, rubber, medicines, vitamins, cosmetics, perfumes, food products, synthetic yarns and fibres, synthetic leathers, glues, pesticides, fertilisers comprising (i) a step of depolymerisation of oxygenated polymer materials according to the method of the invention and optionally (ii) a step of hydrolysis, and optionally (iii) a step of functionalisation and/or defunctionalisation.
