The defects (i.e., the slow vulcanization speeds and the mold corroding tendency) of a known curable composition comprising (1) a polychloroprene rubber and (2) a di- or tri-mercapto-s-triazine compound can be remedied by a novel composition comprising the known composition and (3) a specified polyalkylene polyamine. The novel composition comprises 100 parts by weight of (1), 0.1 to 3 parts by weight of (2) and 0.1 to 2 parts by weight of (3).
