Abstract
Disclosed is a method for customizing a thermoplastic resin in which a thermoplastic resin body, a thermoplastic polymeric component, and an additive component are provided in a container with means for mixing. The thermoplastic resin body is at a first temperature that is above the onset temperature of the melt processing range of the polymeric component. A coating that is a mixture of the additive component and the polymeric component is formed on at least a portion of the thermoplastic resin body. After the coating is applied, the resin body is cooled to solidify the coating composition. The customized thermoplastic resins produced according to the invention may be heated to above the onset temperature of the melt processing range of the resin body, mixed to form a substantially uniform mixture and formed into an article.
