Question

Can you determine the difference

between a polymer blend and a copolymer with IR

spectroscopy?

Answer 1

Answer #1

FT-IR can be used, but it is not accurate as FT-IR shows only the rest of non-reacted monomers.

Also, If polymer is not soluble, you can use FTIR to look for characteristic monomer peaks, they should disappear unless they are present in polymer.
