The High damping rubber for seismic bearing was developed by the structural modification, <i>cis-trans</i> isomerization, of natural rubber (NR). Dimethyl sulfoxide (DMSO), tetramethylene sulfoxide (TMSO), and tetramethylene sulfone, (TMSN) were used for modifiers. The isomerization rates of NR were compared by using the three modifiers. The isomerization rate was -19% in a whole amount for NR. The isomerization of NR gave a high hysteresis loss and lower compression set. The DMSO was more significant for the degree of an activity on the modifiers than that of TMSO and TMSN. Hysteresis loss of the isomeric rubber was about 2.0 times bigger than that of the control (NR), and the compression set of the isomeric rubber was smaller than that of the control. Vulcanization was also remarkably accelerated.
