Abstract
PURPOSE:The titled vulcanizing agent, consisting of a polysulfide polymer containing polyether linkages expressed by a specific formula, and capable of giving a vulcanized article having improved aging resistance, e.g. heat aging resistance, flex cracking resistance, etc. without blooming. CONSTITUTION:A novel vulcanizing agent for rubber consisting of a polysulfide polymer containing polysulfide linkages expressed by the formula[X is 3-6; R is -(CH2-CH2-O)m-CH2-CH2- (m is 3-5); n is 10-300], e.g. obtained by reacting a dithiol with sulfur chloride. The amount of the vulcanizing agent to be mixed with the rubber is preferably 1.0-8pts.wt., based on 100pts.wt. rubber.
