  • Publication number: 20060211803
    Abstract: A modified clay may be made by contacting a clay with an unsaturated cationic compound and an alkoxyamine, or an adduct thereof. The resulting pre-activated clay, which contains a cationic alkoxyamine bound to the clay, may be further treated with a monomer to provide a polymer that is bound to the clay, thereby forming a nanocomposite material. The nanocomposite material may in turn be blended with another polymer prepared from the same or a different monomer.

  • Publication number: 20050266182
    Abstract: This invention relates to thermoplastic articles having printable matte surfaces. The printable matte surface is achieved by blending inorganic particles, and especially silica particles, having a mean particle size of from 2 to 30 micron and a narrow particle size distribution into the thermoplastic at from 15 to 30 percent by weight.

  • Publication number: 20050154140
    Abstract: The present invention relates to core-shell polymers having a hydrophilic copolymer shell, and a high level of core material of from 75 to 95 weight percent. The hydrophilic shell provides better coverage of the core resulting in better powder properties such as anti-blockinig. The hydrophilic shell also allows for a thinner shell and a larger elastomeric core. Core-shell polymers of the invention are especially useful as impact modifiers for plastic materials.
