pKa of a PEI solution

Polymers are not my field, and I have some questions that may sound stupid:

- Do polymers have pKa?

- How could I know the pKa of a PEI (polyehtyleneimine) solution?

- Where could I find a list of polymers with their respective pKa? (I don't know whehter it exists or not).

Thank you

The questions are not stupid, posting them twice is another thing
