Results and discussion
Applicant's summary and conclusion
- Conclusions:
- The substance is used as an accelerator used in rubber industry. The first step during the curing process is the symmetrical cleavage of the substance in 2 radicals: R2 N-CO-S-S-CO-NR2 --> 2 R2N-CO-S*
This radical is able to react with aliphatic chains contained in the rubber matrix.(e.g. isobutylene groups). The radicals are reactive species which are added to double bonds. Thus, the substance is consumed during the vulcanisation step. As isobutylene groups are available in great excess it is most likely that practically no unreacted substance is still present in rubber after vulcanisation - Executive summary:
