  • Biodegradable polymeric nanocomposite compositions particularly for packaging
    Publication number: 20100076099
    Abstract: Specific polymer blends of polylactic acid (PLA) and polyhydroxybutyrate (PHB) and poly-(butylenes adipate-co-terephthalate (PBAT) as a fatty acid quaternary ammonium modified clay. The blends are particularly useful for barrier packaging.
    Type: Application
    Filed: October 21, 2009

  • Methods of making nanocomposites and compositions of rubber toughened polyhydroxyalkanoates
    Patent number: 7420011
    Abstract: Toughened compositions from polyhydroxyalkanoate (PHA), preferably PHB reactively blended with maleated poly butadiene and with an epoxidized natural or synthetic rubber are described. The compositions preferably include clay nanoparticles which can be organically modified and can be exfoliated by the blend. The compositions can be used in a variety of applications, including automotive uses.
