    Abstract: PROBLEM TO BE SOLVED: To provide a polyurethane for reactive coating, which has a high permeability to water and hose binder component can be stored at high humidities. SOLUTION: The isocyanate functional binder comprises a) 20-90% of a copolyether having an average molar mass of 2,500-6,000, an OH functionality of 3 and 5-20 wt.% of ethylene oxide(EO), 90% or more of the EO being of a block form; b) 0-50% of a copolyether having an average molar mass of 1,500-3,000, an OH functionality of 2 and 40-60% of EO, 20% or less of the EO being of a block form; c) 0-30% of a diol having an average molar mass of 1,500-3,000 and containing no EO; d) 10-30% of a diisocyanate having an average molar mass of 140-340; and e) 0-10% of a 2.5-4.5 NCO-functional polyisocyanate, EO in a)+b) being 5-40%, the molar ration of b) to a) being 0-3, the ratio of OH in a)+b)+c) to NCO in d) being 0.5 or less, and has 2-8 wt.% of NCO based on the binder.

    Abstract: The invention relates to the use of macroporous weakly-basic anion exchangers, charged with palladium or platinum and based on crosslinked polystyrene, as catalysts for the removal of oxygen from aqueous media by catalytic reduction, a process for the preparation of these catalyst resins, and new macroporous weakly-basic anion exchangers, charged with palladium or platinum and based on crosslinked polystyrene, in which the amino groups are primary or secondary amino groups.

    Abstract: Removal of O2 from aq. media is effected by catalytic redn. using a catalyst comprising Pt or Pd on a macroporous weakly basic anion-exchange resin based on crosslinked polystyrene. Also claimed are new catalysts of the above type, in which the resin has prim. or sec. amino gps. Redn. is effected with H2, N2H4 or hypophosphite using a catalyst based on a resin with a prim., sec. and/or tert. amino gp. content of 1-2 mole/l, an ave. pore dia. of 50-1000 Angstroms and a surface area of 5-200 m2/g, where the polystyrene is crosslinked with 4-12wt.% divinylbenzene (DVB).
