Estimating the term…
Disclosed herein is a high molecular composite material, which comprises as one component thereof a water insolubilized homopolymer of at least one monomer selected from specific N-alkyl- or N-alkylene-substituted (meth)acrylamides, a second copolymer of said at least one monomer with one or more monomers other than the (meth)acrylamides and copolymerizable therewith, or a water-insolubilized product of the homopolymer or either first or second copolymer. The water-insoluble product can form, with a low or high molecular compound containing one or more active hydrogen or hydrophobic groups, a composite material which may be applied widely for absorbing and desorbing a variety of valuable synthetic compounds and natural matter.
An absorption-desorption method for the separation of water soluble organic compounds from the aqueous solution containing the same wherein the water soluble organic compounds are selected from the group consisting of (a) compounds containing active hydrogen atoms wherein said active hydrogen atoms are present in the form of (1) one or more hydroxyl groups substituted to an aromatic ring or an aliphatic hydrocarbon radical or (2) one or more carboxyl groups substituted to an aromatic hydrocarbon radical or an aliphatic hydrocarbon radical;
