Comparative study of thermal, mechanical and structural properties of polybutadiene rubber isomers vulcanized using peroxide
Three commercial polybutadiene rubber (BR) compounds (high cis, medium cis and high vinyl content) were vulcanized at 433 K, using different amounts of dicumyl peroxide (DCP) as curing agent. To analyze the structural changes produced by the vulcanization process of the three BR isomers, different e...
