摘要:
Aniline copolymers and the synthesis thereof for use as antimicrobial (antibacterial, antifungal or antiviral material) material of for the manufacture of antimicrobial objects, suitable for use in the health, food, packaging, water, paint, wood, textile, poultry, glass, paper, rubber, ceramic, seafood, sports, plastic and agricultural industries. The copolymer may be for example (A): where for example R3═H5—CO2H, —CO2Me, or —CO2Et. R is typically H or a C1-C6 alkyl, x is an integer between 1 and 0 and m indicates the degree of polymerisation. Preferred copolymers are copolymers of aniline with 3-aminobenzoic acid, 2-aminobenzoic acid and ethyl 3-aminobenzoate.
摘要:
A non-leaching mediator may include a polymer comprising the general formula (VIII): and salts thereof, where R′ is an organic group, m is 0 or 1, n is about 9, and x and y independently are an integer from 1 to 10,000.
摘要:
A non-leaching mediator may include a polymer having a polymeric backbone, and a plurality of phenothiazine groups bonded to the polymeric backbone. The plurality of phenothiazine groups may include at least one of a phenothiazine group having the general formula (IV): and salts thereof, where n is about 9 and “R” represents the polymeric backbone to which the phenothiazine group is bonded, and a phenothiazine group having the general formula (V): and salts thereof, where n is about 9 and “R” represents the polymeric backbone to which the phenothiazine group is bonded.

Preferred copolymers are copolymers of aniline with 3-aminobenzoic acid, 2-amonobenzoic acid and ethyl 3-aminobenzoate.
摘要:
A covalent crosslinking of ion-conducting materials via sulfonic acid groups can be applied to various low cost electrolyte membrane base materials for improved fuel cell performance metrics relative to such base material. This proposed approach is due, in part, to the observation that many aromatic and aliphatic polymer materials have significant potential as proton exchange membranes if a modification can increase their physical and chemical stabilities without sacrificing electrochemical performance or significantly increasing the material and production costs.
摘要:
Azo-and/or disulfide-containing polymers for use as drug delivery systems having site-specific release of the drug in the colon are obtained by polycondensation or polyaddition of an azo- and/or polysulfide disulfide containing a, w-dihydroxy or diamino reagent with a suitable a, w-difunctional dicarboxylic acid; disocyanato-, disulfide comonomer. The resulting reduction sensitive polymers are linear macromolecules containing an azo and/or a disulfide bond in their polymer backbone.
摘要:
A light-sensitive polysulfonate contains units derived from an aromatic disulfonyl chloride, units derived from a lightsensitive bisphenol containing the styryl ketone group, and, optionally, units derived from a non-light-sensitive bisphenol. The polysulfonate is useful in preparing photomechanical images such as photoresists and lithographic plates.
