I was wondering if anyone could help with designing a surrogate molecule. I am to design a Styrene Butadiene polymer with disulfide bridges. I have calculated that there are 12 monomers required with only one disulfide bridge (two sulfur atoms). My question really is where does the disulfide bridge go

The Copolymer of styrene and butadiene has only one double bond left. If vulcanisation takes place sulfur can only attack this double bond either in ring or crosslink.
