A method of fabricating plastic products having a preselected color, comprising preparing a dispersion of pigment of the preselected color in cottonseed oil; supplying a preselected plastic resin for the product to be fabricated to a process machine having a rotating screw; furnishing the dispersion to the process machine at a position adjacent to threaded portion of the rotating screw; and blending the dispersion and the resin by rotating the screw.

This invention relates to a composition which is suitable for use in the vulcanization of the rubber. The composition is a non-aqueous water soluble polymer based composition comprising a cationic silicate component. The composition may further include a second cationic additive component which is desirable in a rubber vulcanization process. The invention further relates to a method for preparing these compositions.

Polystyrene waste, such as Styrofoam® waste, and carbon nanofibers may be used to produce highly hydrophobic compositions or composites that can separate oil and water. Methods for purifying an aqueous solution may include: passing the aqueous solution, including a hydrophobic organic substance, over or through a surface including a polystyrene-CNF composition, thereby producing an aqueous product including less of the hydrophobic organic substance; and optionally, passing the aqueous product over or through the surface at least one more time.

An additive for resin kneading contains an organic ultraviolet absorber and/or a radical scavenger, and a polymer having the organic ultraviolet absorber and/or the radical scavenger dispersed. The additive for resin kneading has a median size of 1 .Math.m or more and 100 .Math.m or less.
