    Abstract: PCT No. PCT/EP97/03397 Sec. 371 Date Oct. 28, 1998 Sec. 102(e) Date Oct. 28, 1998 PCT Filed Jun. 30, 1997 PCT Pub. No. WO98/02466 PCT Pub. Date Jan. 22, 1998A process for preparing an aqueous polymer dispersion by free-radically initiated polymerization of free-radically polymerizable compounds I with moderate solubility in water, whose disperse polymer particles contain not only compounds I but also compounds II with a very low solubility in water where a mixture consisting of a portion of the compounds I and consisting of the compounds II is used to produce an aqueous emulsion I with a droplet size /=1000 nm.

    Abstract: The invention relates to a reference electrode for chemical sensors based on ion-selective field-effect transistors (CHEMFETs) in an electrolyte/insulator/semiconductor (EIS) system. The reference electrode consists essentially of an insulator/semiconductor substrate coated with polyglutamate or of a phthalocyaninato-polysiloxane polymer film which is coated with polyglutamate and mounted on an insulator/semiconductor substrate.

    Abstract: Process for production of polymer blends which are suitable as filter aids and are composed of polystyrene and of crosslinked water-insoluble polyvinylpyrrolidones via processing of the two components in an extruder, which comprises melting polystyrene in an extruder and then treating it with the polyvinylpyrrolidone, and adding, to the mixture of the components, from 0.1 to 10% by weight of water, based on the total amount of polystyrene and popcorn polymer, and extruding and comminuting the mixture.
