acid (or acid salt if in basic condition) and hydroxyl group.
Anybody has similar experience?
Thanks! |

I did try using concentrated HCl, the polymer was soluble, but not
hydrolyzed (dilution the HCl concentration to half and the polymer
precipitated out).
I can't use tert-butyl groups because the methacrylate is actually a fused
to a lactone ring.I am trying to ring-opening the lactone ring by hydrolysis.
