    Abstract: Disclosed herein is a high molecular composite material, which comprises as one component thereof a homopolymer of at least one monomer selected from specific N-alkyl- or N-alkylene-substituted (meth)acrylamides, a first copolymer of two or more of the (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 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. Especially, the holding and release of some valuable materials by the water-insolubilized product are disclosed as one application example in detail.

    Abstract: A urine absorbing and holding material comprises either a homopolymer of at least one monomer selected from certain N-alkyl- or N-alkylene-substituted acrylamides and methacrylamides or a copolymer of two or more of these acrylamides and methacrylamides, or a copolymer of at least one of these acrylamides and methacrylamides with one or more monomers other than the said arcylamides and methacrylamides and copolymerizable therewith, the homopolymer or copolymer being a water-insolubilized product. This material, in the form of powder, granules, flakes, fibers or film, can be combined with a fibrous material in the form of a woven fabric, non-woven fabric or a flocculent material, into a useful urine absorbing composite for making up to into a pad, diaper or drawers.

    Abstract: This invention relates to an adsorbent obtained by water-insolubilizing a homopolymer of one of N,N-di-substituted (meth)acrylamides represented by the belowdescribed formula, a copolymer of two or more of the N,N-di-substituted (meth)acrylamides or a copolymer of one or more of the N,N-di-substituted (meth)acrylamides and one or more copolymerizable monomers other than the N,N-di-substituted (meth)acrylamides: or wherein R1 means a hydrogen atom or methyl group, A stands for , n being 4 - 6, or , and R2 denotes a methyl or ethyl group. The thusobtained adsorbent has such a property that it is hydrophobicized to have higher adsorbability when heated and its adsorbability drops when cooled.
