Although SIBRs have been under study for nearly twenty years, there are still not any SIBR industrial products on the market.

The weight content of 1,2 and 1,4 polybutadiene units in both SIBRs and SSBR2003 were quite similar.
Molecular Weight and Polydispersity of SIBRs and SSBR2003
The GPC results of the SIBRs and SSBR2003 before and after oxidative degradation are shown in Figs.

n] of the polystyrene micro blocks present in the three SIBRs were essentially the same and were much lower than the [M.
Dynamic Mechanical Properties of SIBRs and SSBR2003
The tan [delta]-temperature curves of the vulcanized SIBRs and SSBR2003 were determined (Fig.
