epoxy group/polymerization
« on: April 10, 2007, 12:07:53 PM »
I can't find how to polymerize epoxy group containing compound. I mean: which catalyst should I use and under which circumstances?
whenever people agree with me, I always feel I must be wrong

Perhaps an anionic catalyst should be appropriate.

i know, but I'm searching for any example of polymerization of epoxy group containing compound

What about Styreneoxide (Epoxystyrene)
This would be a fairly good starting material for a polymerisation (for all polymerisations, as there are cationic, anionic or (as I'm a radical chemist) RADICAL polmerisations ;-) )...

I would prefer a cationic catalyst e.g. (Lewis-) acids for this reaction. Epoxides are much more reactivce under cationic conditions as they are unter basic conditions, as my experience tells me. You need an activation of the epoxide to have an effective ring opening...
Basic conditions are possible, but "protic" conditions are much more appropriate..

I'm going to use BF3 diethyl ether complex. I think it must work.
