Summary

The induction periods, rate constants, activation ener­gy and order of reaction of cis-1,4-polyisoprene crosilinking with an equimolar mixture of diisopropylthiophosphoryl disulfide (DITPD) with morpholine disulfide (DMDS) and mixtures of dlisopropylthiosphosphoryl tetrasulfide (DIPTT) with morpholine disulfide in the temperature range of 140— 180°C have been determined. The results obtained indicate for a similarity of mechanisms of cis-1,4-polyisoprene crosslinking with thiophosphoryl sulfides and thiuram sulfides.
