the proper of carbon black (CB)-filled natural rubber (SMR-L) compounds, with and without the addition of Alkanolamide (ALK), based on various curingsystems such as efficient, semi-efficient and conventional vulcanisation systems were investigated. The ALK loading was fixed at 5.0 phr. It was found that ALK gave improvements to the cure rate, torque difference, crosslink density.filler dispersion,rubber-filler interaction and reinforcing of CB.
