Abstract: The present invention relates to a composition comprising scattering particles. In particular the present invention relates to polymeric composition comprising scattering particles for lightning applications or light guides. The invention also relates to a process for manufacturing such a polymeric composition comprising scattering particles for lightning applications or light guides. More particularly the present invention relates to a polymeric (meth)acrylic composition comprising inorganic scattering particles for lightning applications or light guides.

Abstract: The present invention relates to acrylic block copolymers synthesized by a controlled free-radical process, and their use as low temperature flow modifiers in oil-based compositions. They are especially useful in modifying the low temperature flow behavior in lubricating oils. The acrylic copolymers are especially useful as pour point depressants in lubricating oil.

Abstract: The invention relates to an amphiphilic multiblock copolymer capable of forming non-covalent crosslinks. The non-water soluble copolymer, having a hydrophilic middle block and hydrophobic end blocks, has a high water transmission or permeation. The copolymer can be used in applications requiring absorption and/or transmission of fluids, the preferred fluids being water or hydrophilic liquids such as glycerin, glycols, and alcohols. One specific use of the amphiphilic multiblock copolymer is as a hydrogel material.

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.
