  • Patent number: 8323436
    Abstract: A transparent, reinforced, composite polymeric fiber that has a polymeric body portion made from a first thermoplastic polymer that is transparent to visible light. The fiber includes polymeric reinforcement elements embedded within the polymeric body portion. The polymeric body portion extends between and about the polymeric reinforcement elements. Each polymeric reinforcement element is formed from a second thermoplastic polymer that is transparent to visible light. The peripheral portion and outer surface of the polymeric body portion defines a peripheral portion and outer surface, respectively, of the transparent, reinforced, composite polymeric fiber. A plurality of the fibers are formed into an array that is processed with a consolidation process to form a transparent, reinforced, composite structure.
    Type: Grant

  • Patent number: 5322866
    Abstract: This invention discloses a method of preparing and extruding biodegradable starch blends into biodegradable products in such a way that preprocessing steps, such as gelatinizing or destructurizing of the starch, are not required. Unprocessed raw starch is combined with biodegradable copolymers such as polyvinyl alcohol (PVOH), or ethylene vinyl alcohol (EVOH), a nucleating agent, and a plasticizer. The combination may be processed using a twin-screw mixer, and blown into a film. The method described in this invention alleviates pre-preparation steps, reduces the cost and time required to prepare and extrude starch-based biodegradable materials, eliminates the need to use expensive pre-processed starch, and results in a substantially completely biodegradable product.
