ABSTRACT:
Single component liquid mercaptan containing polymers having at least two terminal mercaptan groups can be cured rapidly by exposure to atmospheric oxygen in the presence of (1) a thiuram and an iron or manganese salt, oxide, hydroxide or metal complex or (2) an iron or manganese dithiocarbamate. A synergistic effect is obtained when calcium peroxide is added to either or both of the above curing systems.
