This invention relates to a method of reprocessing cured polysulfide and/or polymer- captan elastomers. For the reprocessing, 0.5 to 400 percent by weight cured polysulfide and/or poly- mercaptan elastomers are reacted with liquid di- or polymercapto compounds to form liquid-to-pasty mercapto-terminated prepolymers. The cured polysul- fide and/or polymercaptan elastomers are chemically substantially inert and can be rendered useful in that manner and can be used again as polysulfide and/or polymercaptan sealants.
