Sulphur Vulcanisation of Styrene Butadiene Rubber using
In the vulcanisation of diene rubbers using sulphur and accelerators,the efficiency of sulphur intake during crosslink formation is mainly dependent on the type of accelerator system,structure of the base polymer and temperature of vulcanisation. Unlike natural rubber,in the vulcanisation of styrene butadiene rubber,a copolymer,the crosslink ...

The vulcanizing system of diene rubber
Guanidines are basic accelerators; rarely ever used alone, they are used as secondary accelerators. Analogous in structure are the thioureas, though they are seldom used in diene rubber vulcanisation systems, being kept for some EPDM compounds and foam rubber systems. Accelerators similarly used are aldehyde-
