(I need free hydroxyl on final polyamide)
Dear Jafar,
May you provide a scheme of your synthetic route?
Thanks,
your question is too vague. There are many types of amines and hydroxyl grouo with different reactivity. A simple solution will be to protect the hydroxyl group before doing the polymerisation and removing the PG later.
Approximate concentrations are require in compared with the WHO permissible limts
