Abstract

In the previous paper of this series (I-IV) it was described that metal chloride-halo-organic compound systems had constituted powerful non-sulfur vulcanizing systems. Curing rate of this type of vulcanizer being so high, it had been hard to obtain good mixes on the mill with much quantities of the above chlorides.<br>This paper deals with two attempts to develop the methods of scorch-proof in the curing systems. The results are as follows:<br>(1) Amine derivatives, i.e., phenyl-β-naphthylamine, N, N′-diphenyl-p-phenylenediamine, showed a little effect on scorchproof but oil and abrasion resistance of the vulcanizates decreased.<br>(2) By use of benzyl tin trichloride, in place of stannous chloride, an improved dispersion in rubber matrix was attained and the rubber stocks had an excellent nature of slow vulcanization but the vulcanizate indicated poor physical properties.
