The influence of eight different quaternary ammonium and phosphonium salts on the vulcanization of natural rubber was investigated. The central atom (P or N) of the cation was of minor importance, but the nature of the organic chains greatly affected the rheometrical parameters of the process and the mech. properties of the vulcanizates. Studies of rubber compositions containing binary mixtures of a quaternary salt and the com. accelerators ZDEC, TBBS, TMTD and MBTS showed a synergistic effect, mainly with TBBS and MBTS. With such binary systems, it is possible to reduce the amount of accelerator and improve the vulcanization parameters and the quality of the vulcanized rubber. The anionic complex bis(N-phenylsulfonyldithiocarbimato)zincate(II) (Z), one amine-free exptl. accelerator, was prepared and isolated as tetrabutylammonium (B2Z) and benzyltriphenylphosphonium (H2Z) salts. The H2Z complex salt is a new substance and behaved as an ultra-accelerator, being faster than ZDEC and TMTD. B2Z was a medium rate accelerator, being faster than TBBS and similar to MBTS. In addition, the tensile and tear strength of the specimens vulcanized with the zinc-dithiocarbimate salts were superior when compared to compositions containing the com. accelerators. The differences in the behavior of B2Z and H2Z showed that the zinc-dithiocarbimates are versatile accelerators for natural rubber as the process and the quality of the vulcanizate can be modulated by the choice of the cation.
