Abstract
The present invention relates to various processes that utilize one or more supercritical fluids to disperse various inorganic and organic materials, including crystalline materials, into polymeric compositions, substrates or pre-formed articles without the utilization of melt processing of the polymeric compositions or exposing the various inorganic and organic materials and the polymers (or polymeric precursors) to a hot environment. The present invention also describes the unique properties that can be imparted to a polymer/resin composition or article once it has been subjected to a process according to the present invention versus those normally attributable to conventionally treated/processed polymer materials.
