I m looking for a method allowing identification of monomers such as dimethylaminoethyl methacrylate contained in polyacrylate copolymers.
Does anyone know if it's possible to give back the single monomer by a simple pyrolysis for an identification by GC-MS?
It's don't seems to be the case at 450 or 550Â°C

Same question for monomer as CH2=C(CH3)CONHCH2CH2CH2N(CH3)2

Pyrolysis is going to give you a complex mixture.

Are you looking for extractable monomer or total ?

I have to identify this supposed kind of monomer,probably less than 5 % of the total copolymer and I'm not able to see anything by GC-headspace.
