  • Patent number: 3975334
    Abstract: Insoluble polymeric organotin hydrides of the formula: ##EQU1## wherein P represents an organic polymer backbone; R and R.sub.1 each represent a hydrogen atom, a lower alkyl group of 1 to 5 carbon atoms, an aryl group of 6 to 10 carbon atoms, or an alkaryl or aralkyl group of from 7 to 10 carbon atoms; and n is a positive number greater than 1 are disclosed. Such polymeric organotin hydrides are useful as reagents for reducing organic compounds such as organic halides, ketones, and aldehydes without the different problem of removing dissolved or dispersed tin impurities from the reduced compounds.

    Inventors: Guy A. Crosby, Patrick M. Saffron
  • Patent number: 3940503
    Abstract: Translucent substrates such as foodstuffs are colored by adding polymeric dyes. The dyes contain from 0.1 to 2.0 parts of nonchromophoric material for each part by weight of chromophore and are added in a weight amount equivalent to from 0.4 to 0.9 times the weight of monomeric chromophore required to give the equivalent visual shade.

    Inventor: Nicolo Bellanca
  • Patent number: 3937851
    Abstract: Viscoelastic materials such as gelled food products are differently colored in zones with polymeric dyes. When a polymeric dye is added to a zone of a viscoelastic material, such as a gelled food product, it does not migrate from the zone; thus permitting an essentially permanently multizoned colored product.
