Process for producing customized thermoplastic resins

A method for producing an article, comprising the steps of:

• (a) providing in a container with means for mixing a thermoplastic resin body that is at a first temperature, a thermoplastic polymeric component, and an additive component, wherein said first temperature is above the onset temperature of the melt processing range of the polymeric component;
• (b) mixing the thermoplastic polymeric component and the additive component with the thermoplastic resin body so that a coating is formed on at least a portion of said thermoplastic resin body, wherein the coating is a mixture of the additive component and the polymeric component;
• (c) cooling the coated thermoplastic resin body below the onset temperature of the melt processing range of the coating composition to produce a customized thermoplastic resin;
• (d) heating the customized thermoplastic resin to above the onset temperature of the melt processing range of the resin body;
• (e) mixing the resin body and the coating composition to form a substantially uniform mixture;
• (f) forming an article from the mixture.
