Abstract
An ionomeric nanocomposite that includes a base component of a propylene-based polyolefin-metal salt component and a nanostructured material. Optionally, the blend further contains a polymeric component including an ethylene ionomer, a styrenic block ionomer, a hydrogenated styrene-butadiene random copolymer, or a combination thereof. Such ionomeric nanocomposites have increased scratch and mar resistance while still retaining clarity and thermal stability. Methods of preparing such blends, as well as resultant articles including such blends, are also part of the invention.
Claims20
An ionomeric nanocomposite comprising:
- a nanostructured material;
- and
- a propylene-based polyolefin-metal salt component that is a reaction product of at least one propylene-containing homopolymer or copolymer and at least one organic monomer containing at least one hydrophilic moiety, the reaction product being sufficiently neutralized with a metal ion component to decrease the opacity of the ionomeric nanocomposite.
A method of preparing an ionomeric nanocomposite which comprises:
- providing 100 parts by weight of a propylene-based polyolefin-metal salt component, from about 0.0001 to 200 parts by weight of nanostructured material, optionally a polymeric component, and optionally a property-modifying agent;
- melt blending the components sufficiently to provide a blend that is at least substantially homogeneous.
