    摘要： The cross-linking or curing of thermosetting resins and of hot curable elastomers is carried out by heating the mate­rial or the article comprising the resin (or the elastomer) by means of saturated vapour of a commercial perfluoropolye­ther having an average boiling point corresponding to the temperature necessary for the cross-linking and having a boil­ing point range not exceeding 12°C (measured according to ASTM D 1078) in the presence of a chlorofluorohydrocarbon seconda­ry vapour.
