  • Publication number: 20080207801
    Abstract: A polymer nanocomposite contains layered clay dispersed in a polymer matrix together with compatibilizers for the clay and polymer matrix. The compatibilizers are a combination of two or more graft polymers. One graft polymer has high functionality and short chain length and another graft polymer has low functionality and long chain length. Such polymer nanocomposites have improved dispersion and better strength and modulus, while maintaining good toughness and impact strength. The polymer nanocomposites are particularly useful in applications where good mechanical performance and light-weight are of importance.

  • Patent number: 7041716
    Abstract: The present invention provides a thermoplastic composite comprising: a polyolefin; a cellulosic filler; a carboxylic acid and/or carboxylic acid anhydride graft polyolefin having an acid number greater than 15 mgKOH/g; and, a basic reactive filler present in an amount of 5–25 wt %, based on the weight of the composite. Such composites may be used in structural and non-structural applications and exhibit improved mechanical properties, thermal properties and/or resistance to biological degradation.
