hello, I want to react polymer with TMC. My polymer has active amine group. I don't know how to quantify NH2 groups in my Polymer which is required to calculate the moles needed of TMC for such reaction. I think there's a back titration method but I don't exactly know the reagents. Can anyone help me please.
You can carry out iodometric titration for estimation of aromatic amine similar to estimation of aniline by iodometric method using brominating solution.
if you are looking for an aromatic amine occurrence in your polymer, you can use crude HNMR of your polymer and a standard with a characteristic pick. To do that, you need to find a characteristic pick of the aromatic amine moiety which is not exchangeable with water if you are using
water as solvent.
