    摘要: Cured aminoplast resins are recycled by a process in which said resins, which may contain fillers, are treated with an aqueous sulfite, hydrogen sulfite or disulfite solution and the resulting low molecular weight degradation products are used in chemical processes. The resulting low molecular weight degradation products of cured aminoplast resins are used for coating moldings, for tanning leather and skins and for the production of moldings which contain cured aminoplast resins or consist thereof.
