Process for removing residual monomers and oligomers from amine-containing polymers

Treatment of amine-containing polymers with strong acid, cation exchange resins from aromatic copolymer crosslinked with 2 - 25% crosslinker, followed by ultrafiltration with a membrane filter having a molecular-weight cutoff, measured against the polymers to be treated, of about 10,000 to about 15,...
