Abstract: The invention relates to an amphiphilic block copolymer, to the preparation thereof, and to the use thereof in the form of a self-stabilizing latex. The copolymer has the formula R5O—[—CH2CH2—O—]n—C(?O)—CR3R4—[CH2CR6R7]m—S—C(?S)—S—R1 where: R1 is a straight or branched alkyl group, an alkenyl group having one or more —C?C— bonds, or an alkynyl group having one or more —C?C— bonds, said groups including 8 to 18 carbon atoms; 20?n?100; R3 and R4 each are independently H, an alkyl group with 1 to 4 carbon atoms, or a nitrile group, at least one of R3 and R4 being different than H; R6 is a phenyl group or an alkoxycarbonyl group in which the alkoxy group includes 1 to 8 carbon atoms; R7 is a hydrogen atom or a methyl radical; and 20?m?1000.

Abstract: One or more reaction zones are formed as channels in a carrier. Each reaction zone is lined with a color indicator and the carrier is improved in that a coating of the reaction zone is realized wherein the coatings are individually changeable and the coating is easily carried out with uniform coating density and, if required, with different indicators. This is achieved with a carrier which is configured as a sandwich-like composite foil which includes a reagent carrier foil which, in turn, is made of a special plastic material. This plastic material can be perfluoroethylene propylene (FEF) which is surface treated by a corona discharge and is then known as FEPc. An especially advantageous embodiment for the reaction zones on the reaction carrier foil is that the reaction partners are applied to the reagent carrier foil in the form of a point matrix applied by a microdrop generator.
