In this paper, the results are described which were obtained when : Natural rubber studied in previous paper was replaced by SBR, the initial temperature of Banbury mixer was set at 30°C, supplying of cooling heat water was then stopped and the content was milled for 0, 10 and 20 minutes and heated by the produced at the stage of milling.<BR>As the result, disadvantages of silica were eliminated through heat-treatment; then, in order to give full justice to the effect as in the case of natural rubber, an attempt was made to find out the optimum condition from those illustrated below : <BR>Initial temperature of Banbury mixer : 30, 60 and 90°C, <BR>Duration of heat-treatment : 0, 10 and 20 minutes.<BR>As the result, a compound was obtained with physical properties due to elongation and dynamic properties which were nearly satisfactory when the initial temperature was from 60°C to 90°C and time of heat-treatment was 10 minutes.
