  • Rapidly expanding starches with altered crystalline structure
    Patent number: 6846497
    Abstract: This invention relates to a starch based tablet disintegrant useful at low addition levels and providing equally effective properties in water and physiological fluids. The starches are characterized by their low solubility in cold water, high swelling power and labile birefringence in the dry state, which rapidly disappears upon addition of water. The preferred starches are inhibited then processed to remove a portion of the granular structure.

  • Starches for use in papermaking
    Patent number: 6843888
    Abstract: This invention relates to a degraded, inhibited cationic starch for use in papermaking systems, which affords improved physical properties, particularly strength. Additionally these derivatives provide easy-to-prepare alternatives totraditional starches, and can even be added directly to the papermaking process without cooking. While the benefits of these starch compositions can be applied to any type of papermaking method, they are especially useful in high shear, high conductivity and recycle systems.

  • Dispersions containing living radicals
    Patent number: 6841636
    Abstract: The present invention relates to a dispersion of polymer particles, the particle containing, on average, more than 1 living radicals each, the radicals not being chemically protected. The invention is also directed to a free radical polymerization process resulting in a dispersion containing polymer particles having on average one or more living radicals. The process involves carefully regulating the polymerization conditions to produce small size particles under monomer-starved conditions containing, on average, more than one living radical in every particle. These living polymer radicals can be further reacted to form polymers with a controlled architecture.

  • Rate matched copolymerization
    Patent number: 6828393
    Abstract: This invention relates to a method for controlling copolymer architecture by a two-part process. In the first step, a monomer analysis is obtained from a test polymerization having constant rate co-monomer addition. In the second step a copolymer is polymerized using a co-monomer feed rate that has been adjusted based on the monomer analysis to produce a copolymer with highly controlled polymer architecture. The method can predict feeds rates to produce any desired polymer architecture from a purely random polymer to a tapered polymer. The method works for terpolymers as well as copolymers.

  • Method of grain production for heterozygous waxy sugary-2 maize
    Patent number: 6828474
    Abstract: This patent pertains to a method of producing a waxy maize starch derived from a plant which is heterozygous for the recessive sugary-2 allele by interplanting waxy maize seed which is homozygous for the dominant sugary-2 allele and waxy maize which is homozygous for the recessive sugary-2 allele, one hybrid being male sterile. The maize is harvested and processed together to obtain starch with excellent low temperature and freeze-thaw stability, high pasting temperature, and intact granules.
