ABSTRACT:
An improved liquid carrier system for dispersing into polymeric compositions various modifying ingredients such as pigments, colorants, organic dyes, and other additives is disclosed. The additive carrier system is used for coloring and for compound polymers either by coating the resin with the liquid additive prior to processing, or preferably, by metering said additive directly into an extruder or molding machine which is used to manufacture the polymer product in any of its various forms, e. g. pellets, fibers, films, sheets, and other plastic materials.
