The effects of two type active filler (carbon black and silica) on the characteristics of elastomers based on natural rubber and chlorosulphonated polyethylene rubber blend blend (NR/CSM) were investigated. For cure studies, torque-time curves were registered at different temperatures (150, 160 and 170°C). It was estimated that higher curing temperature cause decreas of the cure plateau torque and lead to higher crosslinking rate constant.Physical chemistry 2008 : 9th international conference on fundamental and applied aspects of physical chemistry; Belgrade (Serbia); 24-28 September 200
