Abstract: Metal complexes of 8-hydroxyquinoline and polymeric water-insoluble but water-swellable cross-linked N-vinyllactam or N-alkyl-N-vinylamide polymers in the form of porous beads or granules and a process for preparing same. Such complexes are particularly suited for use as algicides, fungicides, slimicides, and bacteriocides in the treatment of water such as in gravity filtration systems, canisters or packed columns having the advantage of rapid throughput. The complexes may be prepared by adsorbing the hydroxyquinoline onto the cross-linked N-vinyllactam or N-alkyl-N-vinylamide in the form of porous beads or porous granules and subsequently forming the metallic complex in solution.

Abstract: An interpolymer useful in the thickening of aqueous acids comprising (A) about 20 to about 99.0 mole % acrylamide or N-vinyllactam, (B) about 0.5 to about 10 mole % long-chain containing vinyl monomer derivatives having the formula: ##EQU1## wherein Y represents hydrogen, halogen, lower alkyl or phenylX represents oxygen, sulfur, carboxy or carbonamido; andR represents a hydrocarbon group containing from about 6 to about 36 carbon atoms including normal chain alkyl, branched chain alkyl, cycloalkyl and alkylaryl and (C) about 0.5 to 79.5 mole % of a cationic moiety.

Abstract: Phenolic complexes of water-insoluble but water-swellable crosslinked N-vinyllactam or N-alkyl-N-vinylamide polymers in the form of porous beads or granules and a process of preparing same. The complexes are particularly suited for use in situations wherein phenolic materials in limited quantities are desired such as, for example, in canisters or columns which are used to treat liquids or water. The novel complexes are prepared by adsorbing a phenolic material onto the porous granular or porous bead-like crosslinked N-vinyllactam or N-alkyl-N-vinylamide polymers.
