Abstract
Influence of the styrene content on the retraction behaviors of SBR vulcanizates was studied. SBRs with different styrene contents of 15 and 21 wt% were used. The vulcanizate with low styrene content started to recover at lower temperature than that with high one. The recovery rate of the vulcanizate with low styrene content was slower than that with high one. The recovery difference between the two vulcanizates with different styrene contents was larger for the carbon black-filled vulcanizates than for the silica-filled ones. The experimental results were explained with the glass transition temperature and modulus.
