Abstract

This invention relates to the use of catalyst systems containing (a) dibenzothiazyl disulphide, (b) carboxylates and/or organic complex compounds of manganese, iron, nickel or cobalt and (c) organic bases selected from the group consisting of guanidines and tertiary amines optionally containing inert substituents, as reaction accelerators for the oxidative hardening of plastics precursors containing mercapto groups.
