    摘要： In a reagent strip for the dry-chemical detection of a component of an aqueous sample solution comprising a detection reagent in a membrane, the improvement wherein the membrane is an essentially anhydrous, but water-absorbing, membrane for a reagent substrate in an analytical agent for the dry-chemical detection of a component of an aqueous sample solution, comprising at least one hydrophobic film-forming, water insoluble organic polymer in which at least one hydrophilic organic polymer is dispersed as discrete particles. The reagent can be incorporated into the membrane when produced or can later be applied as by impregnation. The membrane performs as well as or better than multi-layer strips.

    摘要： An uncrosslinked copolymer of comonomers (a), (b) and (c) and containing reactive double bonds, the comonomers based on the total mols of (a), (b) and (c) comprising(a) 45 to 99.9 mol-% of at least one ethylene containing 1 to 4 fluorine atoms,(b) 0 to 54.9 mol-% of at least one comonomer selected from the group consisting of(b1) a linear or branched C.sub.3-8 alkene containing at least one fluorine atom,(b2) an alkyl vinyl ether containing at least one fluorine atom,(b3) an open-chain or cyclic C.sub.3-6 ketone containing fluorinated .alpha.,.alpha.'-positions and(b4) non-fluorinated C.sub.2-4 alkene, C.sub.3-6 alkyl vinyl ether or C.sub.4-6 vinyl ester, and(c) 0.1 to 5 mol-% of at least one unconjugated diene. They are produced by radical polymerization. Because of the absence of bromine and/or iodine, during subsequent peroxidic cross-linking no toxic alkyl bromide and/or iodide is released.
