Studies on the Combined Use of Some Different Organic Accelerators. IV. Diphenylguanidine and Dibenzothiazole Disulfide

Abstract

Abstract 1. Diphenylguanidine and dibenzothiazole disulfide do not form a molecular compound or eutectic mixture, as judged by their melting and softening point curve. 2. The effects of scorching were studied by the use of various proportions of diphenylguanidine and dibenzothiazole disulfide; the maximum scorching was found with the mixture which had the lowest melting point in the curve. 3. These proportions were also studied for their vulcanizing power. 4. Diphenylguanidine and dibenzothiazole disulfide form a molecular compound through the medium of hydrogen sulfide. 5. This molecular compound was prepared and tested for its vulcanizing properties.
