NICHTWÄSSRIGE POLYMERE REAGENZZUSAMMENSETZUNGEN UND DEREN ANWENDUNGEN

Non-aqueous, polymeric reagent film compositions for use with analytical test devices of the dry chemistry type are described. The film compositions are prepared from an organic solution of a copolymer formed by interaction of at least two monomers wherein (a) the first monomer is a hydroxylated acrylate of the general formula where R1 is hydrogen or, more preferably, methyl, and R2 is a hydroxyalkyl group having from 1 to 5 carbon atoms, and (b) the second monomer is a neutral acrylate of the general formula where R1 is hydrogen or, more preferably, methyl, and R3 is a substituted or unsubstituted alkyl group having from 1 to 8 carbon atoms. Preferably, a third monomer is also included which is an amine-containing acrylate of the general formula where R1 is hydrogen or, more preferably, methyl, and R4 is a substituted or unsubstituted aminoalkyl or glycidyl group having from 1 to 5 carbon atoms or a surfactant polyethylene glycol group having from 10 to 30 carbon atoms. The film further comprises at least one enzyme in powder form dispersed therein and, optionally, a chromogenic indicator. The film composition is especially useful for determining components in body fluids, for example, for detecting glucose in whole blood, by rapid techniques.
