  • Patent number: 10323131
    Abstract: The invention is a composition that can prevent formation in, or scavenge undesirable organic materials from, a polymer matrix. The composition contains cyclodextrin and particles of activated carbon. The composition can scavenge thermal decomposition products that can be produced during melt processing of a polymer, contaminants inherent in a polymer, or other types of impurities from a polymer matrix that otherwise may elute into the air, a water supply, or an ingestible material such as a food, a drug, or a beverage. Other aspects of the invention are blends of the composition with polymeric materials, methods of making blends, articles containing the composition, and methods of making articles containing the composition.

  • Patent number: 8913863
    Abstract: A hydrocarbon application cable of reduced nylon with increased flexibility and useful life. The cable may be of a hose or solid configuration and particularly beneficial for use in marine operations. A power and data communicative core of the cable may be surrounded by a lightweight intermediate polymer layer of a given hardness which is ultimately then surrounded by an outer polymer jacket having a hardness that is greater than the given hardness. Thus, a lighter weight polymer is provided interior of the outer polymer jacket, which may be of nylon or other suitably hard material. As such, the overall weight and cost of the cable may be substantially reduced.

    Abstract: The development described provides methods of producing functionalized cellulose in a one-step acid treatment process and of using the cellulose so derived to make composite polymer materials. The composite materials may include mixtures of the acid treated cellulose, functionalized cellulose polymers, including but not limited to cellulose acetate, cellulose butyrate, cellulose propionate, methyl cellulose, and ethyl cellulose, biobased and/or biodegradable polymers, impact modifying agents, and other components such as nucleating agents and pigments. The composite materials formed possess thermomechanical properties that differ from those of similar polymer composites made using prior art. In particular, the composite and nanocomposite materials are characterized by increased heat distortion temperatures and improved impact strengths.
