   I was more successful with both Google and Sigma-Aldrich
by entering Bis epoxide. However, I don't know that anything
I found is helpful. Google comes up with a tremendous amount
of stuff, mostly advanced chemistry. Of course, my search
was only a casual one, looking at only a few of the sites,
so you may may very well do better.
