Studies on crosslinking of cis-1,4-polyisoprene with diisopropylthiophosphoryl sulfides and their mixtures with morpholine disulfide
Studies on crosslinking of cis-1,4-polyisoprene with diisopropylthiophosphoryl sulfides and their
mixtures with morpholine disulfide
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.
