摘要:
Anion-binding polymers are described. The anion-binding polymers in some cases are low swelling anion-binding polymers. In some cases, the anion-binding polymers have a pore volume distribution such that a fraction of the polymer is not available for non-interacting solutes above a certain percentage of the MW of the target ion for the polymer. In some cases, the anion-binding polymers are characterized by low ion-binding interference, where the interference is measured in, for example, a gastrointestinal simulant, relative to non-interfering buffer. Pharmaceutical composition, methods of use, and kits are also described.

摘要:
Sensors for determining the presence and concentration of bio-molecules in a biological sample are provided in the form of polymer brushes, which comprise a substrate having a surface that is modified with a water-dispersible or water-soluble polymer segment having functional groups that bind probes. The method of synthesis of such sensors preferably includes use of controlled free radical polymerization techniques, and in particular the use of an iniferter initiator, which allows for controlled architecture polymers to modify the surface of the substrate. In this manner functional groups in the polymer chain are removed from the surface, which allows for solution chemistry to be more realistically reproduced with the benefits of a solid bound probe.
摘要:
A method of free radical polymerization and for cleaving a thio group from the resulting polymer is provided. The method comprises forming a mixture of one or more monomers, at least one free radical source and a chain transfer agent, wherein the chain transfer agent comprises a thio moiety. The mixture is polymerized, and the resulting polymer is mixed with a free radical source, and a monomer having little or no homopolymerizability under cleavage conditions. The thio moiety on the polymer is replaced with a group of interest.

摘要:
Low MFFT aqueous polymer dispersions of film-forming, relatively low Tg ethylenic/carboxylic polymer particulates, e.g., styrene/alkyl acrylate/acrylic acid copolymer particles, are well adapted for the production of wear- and soil-resistant coatings and adhesives, and include an effective, at least partially "neutralizing" amount of a polyoxyalkyleneamine, e.g., a polyoxyalkyleneamine bearing at least one primary and/or secondary amine functional group.
