Abstract

PURPOSE: To inhibit the premature vulcanization of rubber, by adding an N-substituted benzothiazole-2-sulfonamide compound to natural rubber or a diene synthetic rubber containing sulfur or a sulfur-containing vulcanizing agent or accelerator.
CONSTITUTION: The premature vulcanization of rubber is inhibited to upgrade the quality of rubber products and material loss due to scorch is prevented by adding an N-substituted benzothiazole-2-sulfonamide compound (e.g. N-cyclohexylthio-N- cyclohexylbenzothiazole-2-sulfonamide, etc.) of formula I, where R is benzothiazolyl or substituted benzothiazolyl of formula II (where X is halogen, lower alkyl, lower alkoxy, acetamido, or nitro); R' is H, alkyl, benzyl, phenyl, substituted aryl of formula III (where Y is halogen, lower alkyl, or nitro), or naphthyl, etc. to natural rubber or a synthetic rubber containing sulfur or a sulfur-containing vulcanizing agent (e.g. morpholine disulfide, etc.) or accelerator (e.g. thiazoles, sulfenamides, etc.).
