ABSTRACT:
Novel polymers are described herein which are particularly useful in removing phenolics from waste streams. The polymers are prepared by reacting an oxazoline or oxazine (preferably 2-methyl or ethyl-2-oxazoline) with a cross-linked vinylaromatic polymer bearing pendant halomethyl groups on the aromatic rings. Macroporous beads prepared by reacting cross-linked chloromethylated polystyrene with 2-methyl and/or 2-ethyl-2-oxazoline are particularly useful embodiments in removing phenolics from aqueous waste streams and are used to remove phenolics (e.g. tannins) and other color-bodies from bleached Kraft pulp effluent.
