I recently found that formic acid will actually eat holes in thin films of PMMA. This resulted in a pitted PMMA surface everywhere there had been a drop of formic acid. I know formic acid is a solvent for PMMA, but how could the PMMA be cut into pieces small enough to be evaporated? There is a possibility of the formic acid inserting itself at the oxygen attached methyl group but how would that create the observed pits? Any advice or direction as to where I should look would be much appreciated. I guess an answer would be good too.
