CONCENTRATE COMPOSITIONS FOR IMPARTING A TRANSLUCENT OPTICAL EFFECT TO TRANSPARENT THERMOPLASTIC POLYMERS.

摘要

The invention provides compositions and methods for imparting translucent optical effects to transparent thermoplastic polymers. The compositions comprise the polymer and 0.01 to 10 parts per hundred by weight of a particulate, light-scattering material comprising an average particle diameter of from about 0.1 microns to about 200 microns. The particulate material may be organic or inorganic and be in the form of powders, flakes, platelets, fibers, whiskers, and mixtures of these. The translucent optical effects are obtainable in a continuum of very smooth to very grainy, depending on the type and concentration of the particles employed.
