A high molecular composite material has, as one component thereof, a homopolymer of at least one monomer selected from specific N-alkyl- or N-alkylene-substituted (meth)acrylamides, or a first copolymer of two or more of the (meth)-acrylamides or a second copolymer of said at least one monomer with one or more monomers other than the (meth)-acrylamides and copolymerizable therewith. Alternatively, the said component can be a water-insolubilized product of the homopolymer or either first or second copolymer. The homopolymer, copolymer or 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 holding and releasing a variety of valuable synthetic compounds and natural matter. |
