Abstract: The present invention relates to a method for sequestering bile acids in a patient and to particular polymers for use in the method. The method comprises administering a therapeutically effective amount of a guanidinium moiety-containing polymer composition to a mammal, such as a human, whereby bile acids are sequestered. The polymers of the invention comprise guanidinium moieties and optionally, additional substituents such as a hydrophobic group, a quaternary ammonium-containing group or a combination thereof.

Abstract: A method for removing bile salts from a patient by ion exchange by administering to the patient a therapeutically effective amount of one or more highly crosslinked polymers characterized by a repeat unit having the formula ##STR1## or copolymer thereof, where n is an integer; R.sup.1 is H or a C.sub.1 -C.sub.8 alkyl group; M is ##STR2## or --Z--R.sup.2 ; Z is O, NR.sup.3, S, or (CH.sub.2).sub.m ; m=0-10; R.sup.3 is H or a C.sub.1 -C.sub.8 alkyl group; and R.sup.2 is ##STR3## where p=0-10, and each R.sup.4, R.sup.5, and R.sup.6, independently, is H, a C.sub.1 -C.sub.8 alkyl group, or an aryl group, the polymers being non-toxic and stable once ingested.

Abstract: An amine polymer includes a substituent bound to an amine of the polymer. The substituent includes a quaternary amine-containing moiety having at least one hydrophobic moiety. A method for binding bile salts of bile acids in a mammal includes orally administering to the mammal a therapeutically-effective amount of the amine polymer.

Abstract: An amine polymer includes first and second substituents bound to amines of the polymer. The first substituent includes a hydrophobic moiety. The second substituent includes a quaternary amine-containing moiety. A method for binding bile salts of bile acids in a mammal includes orally administering to the mammal a therapeutically-effective amount of the amine polymer.

Abstract: Phosphate-binding polymers are provided for removing phosphate from the gastrointestinal tract. The polymers are orally administered, and are useful for the treatment of hyperphosphatemia.

Abstract: Iron binding polymers are provided for decreasing the absorption of iron from the gastrointestinal tract. The polymers are orally administered, and are useful for treatment of iron overload disorders.

Abstract: A method of providing a substrate with a thin film coating of multiple layers by a single immersion of a substrate having active hydrogens on its surface into a coating solution including two or more dissimilar hydrolyzable and condensable organometallic compounds, water, a solvent, and a base, the solution having undergone substantially no polymer growth, for a time sufficient to form in situ the film on the substrate, removing and drying the coated substrate.

Abstract: A method of coating a substrate with a uniform, ultra-thin film of a polymer comprising immersing a substrate having active hydrogens on its surface in a solution comprising at least one hydrolyzable metal alkoxide of a polymeric network-forming cation, water, a solvent and a base, said solution having undergone substantially no polymer growth, for a time sufficient to form in situ said film on said substrate, removing and drying said coated substrate.

Abstract: A method for bonding a metal substrate to a similar or dissimilar substrate by first applying a primer coating to the surface of the metal substrate and then bonding the primed metal substrate to the other substrate. At least part of the primer coating is composed of a uniform, ultra-thin film that is formed by immersing, prior to bonding, the metal substrate in a solution that has undergone substantially no polymer growth. The solution contains at least one hydrolyzable metal alkoxide of a polymer network-forming cation, water, a solvent and a base. The metal substrate is allowed to react with the solution for a time sufficient to form in situ an ultra-thin film on the metal substrate.

Abstract: An adhesive composition useful for bonding thermoplastic elastomers to substrates such as metal that contains a halogenated polyolefin that has been chemically modified to contain a polyhydroxylic aromatic compound and/or a sulfur-containing compound. The modified polyolefin is preferably prepared by first reacting the polyolefin with an acid anhydride and then reacting the anhydride-modified polyolefin with the polyhydroxylic aromatic compound and/or the sulfur-containing compound.
