抄録
In the previous paper we had shown that the reagent of the structure of CH3-X-C-=Y-ZH had effect of secondary vulcanization accelerator to rubber in the presence of dibenzothiazyl disulfide (DM) and we suggested a mechanism of acceleration by using quantum chemical calculation.<br>As the results, the scorch time, Δt, of rubber ingrediated with the secondary vulcanization accelerator was shown to correlate linearly with its resonance stability, ΔE.<br>It is proposed that the reaction takes place DM and secondary vulcanization accelerator to form six- membered ring complex and in the case of non-sulfur vulcanization its radical abstracts hydrogen followed by to dissociate into unstable radicals. And in the absence of sulfur the radical from accelerator abstracts hydrogen atom from rubber molecule and in the presence of sulfur it may attack sulfur ring to form sulfur radicals and cross-linking of rubber may be brought about.
