grafting of a thin layer on pmma

Hi everyone,



I'm actually looking for a way to graft chemically a thin layer of a compound which will finally comprise at least one available amine function on a PMMA substrate, the final goal being to make an epoxy reaction on the surface of the substrate. I thought of a transesterification, but my chemistry isn't what it once was, so I don't know if such a reaction is feasable at 25=B0C with a good yield on PMMA. Does the idea sound good ? Any suggestion about what can be done ?


CH3 CH3 | |



-(CH2 - C)n - + NH2 - R - OH -> - (CH2 - C)n - + CH3OH | | CO(OCH3) CO(O-R-NH2)

Maybe reacting the amine directly with the ester to form an amide, and then reduce the amide? R-CO(OCH3) + NH3 --> RCONH2 + CH3OH --> RCNH2. It doesn't look like you need the ester group, do you?

I imagine that finding conditions that don't dissolve/craze the PMMA would be the challenge, especially regarding the CH3OH.
